Our offer of Smith-Blair repair clamps

At our warehouses in Rochester, Avoca, and Watertown, we carry several configurations of Smith-Blair repair clamps for sale, including full-circle Redi clamps and single-band full-circle options that can be used for repairing a diverse range of pipe materials and types of damage. We also carry service saddle products used for branch lines, service connections, and other utility applications.

Smith-Blair 226 Single Band Full Circle Repair Clamps

Smith-Blair 226 full circle repair clamps are used for swift and economical repair of full circumferential breaks, cracks, holes, or other kinds of damage or deterioration on different pipe materials, including cast iron, asbestos cement, aluminum, fiberglass, steel, plastic, and more. This Smith-Blair repair clamp can fit a number of outside diameters within its nominal size range and features a full-circle band that distributes pressure around the pipe, up to 300 PSI working pressure, and a Flexi-Coat® epoxy finish for corrosion resistance.

Smith-Blair 244 Full Circle Redi Clamp

For rigid steel, plastic, or copper tube with pin holes, punctures, or splits, Smith-Blair 244 full-circle Redi clamps provide a fast and economical option. The full circumferential gasket includes bonded and recessed armor plates, allowing the clamp to seal 360 degrees around the pipe, while stainless steel bands, ductile iron lugs, and a drop-in bolt design help make field installation more efficient for crews looking for a Smith-Blair full circle repair clamp.

Smith-Blair 245 Redi Clamp

Rough or pitted pipe surfaces often require a Smith-Blair clamp that can conform closely to irregular areas. These Smith-Blair 245 Redi clamps are designed for pin holes, punctures, or splits, with finely gridded gasket surfaces that help seal rough or uneven pipe. The electro-galvanized carbon steel bolts include a dichromate seal to resist corrosion, while the generous bolt shoulder helps secure the bolt against turning during tightening.

Smith-Blair 261 Single Band Full Circle All Stainless Steel Repair Clamps

If you are looking for a clamp that can be used to repair virtually any kind of damaged or deteriorated pipe up to 12 inches in diameter, the Smith-Blair 261 stainless steel repair clamp is one of the best options you’ll find in our Rochester, Watertown, and Avoca warehouses and our online catalog. Its premium stainless steel construction provides strong corrosion resistance and supports fast, long-lasting repair on damaged pipe.

Smith-Blair 274 Bell Joint Leak Clamp

When a leak is located at a bell-and-spigot joint rather than along the pipe barrel, Smith-Blair bell joint leak clamps offer a more targeted solution. The Smith-Blair bell joint leak clamp 274 is made to seal or help prevent leaks in caulked or rubber ring joints, using Kee-Lok gaskets and Bell-Spigot rings that can fit both joint types on many cast iron or ductile iron pipe applications, with several common listed sizes, including 4-inch, 6-inch, 8-inch, 10-inch, and 12-inch options.

Smith-Blair 313 Double Bale Service Saddle

For service-line work, Smith-Blair 313 double-bale service saddles can be used for branch lines, instruments, air and vacuum valves, and other pipe appurtenances. This ductile iron service saddle includes a TaperSeal™ gasket and wraparound bales, with a wide saddle body for stability and threaded outlet options from 5/8 inch through 4 inches, making it a relevant part of Blair Supply’s selection of Smith-Blair fittings.

Smith-Blair 372 Service Saddle CC/AWWA Outlet

A stainless steel option is also available for PVC pipe and other compatible pipe types. These Smith-Blair 372 service saddles are designed to provide uniform sealing and pipe support without crushing action, with 304 stainless steel construction, a molded outlet gasket, and a keeper bar that helps pull and close the clamp during installation.

Our offer of Smith-Blair couplings

In addition to our Smith-Blair repair clamps for sale, we also offer several different pipe connectors and couplings designed for industrial and commercial applications. Our selection includes compression-style options, steel fabricated products, and OMNI models for different connection needs, OD ranges, and pipe materials.

Smith-Blair 525 Compression Couplings

When plain-end pipes of the same diameter need to be joined, Smith-Blair compression couplings provide a simple and reliable option for compatible PVC, steel, and copper applications. This type of Smith-Blair pipe coupling is available online in 1/2-inch, 3/4-inch, 1-inch, 1 1/4-inch, 1 1/2-inch, and 2-inch sizes, with ductile or malleable iron construction, a galvanized finish, Nitrile gasket sealing, and 2 degrees of deflection per end.

Smith-Blair 411 Steel Couplings

This type of pipe coupling brings several distinct advantages for industrial piping systems. Thanks to their flexibility and ease of installation, they maintain pipe continuity, retain the contents of the line under heavy internal pressure, and help prevent infiltration. A Smith-Blair 411 coupling is designed as a steel-fabricated, bolted sleeve-style solution for plain-end pipes of the same outside diameter, with no welding, special pipe-end preparation, or additional fittings required.

Smith-Blair 441 OMNI Couplings

Our line of OMNI couplings provides a practical method for reducing stocking requirements and joining a vast array of pipe sizes and types. OMNI couplings can fit virtually all types of piping within their specified range, including asbestos cement, cast iron, and aluminum. The Smith-Blair 441 OMNI coupling uses ductile iron sleeves with interchangeable color-coded follower flanges and gaskets to accommodate different OD ranges in the field.

How do you fix a hole in a pipe with a Smith-Blair repair clamp?

Damage in a commercial piping system can have serious consequences unless the issue is mitigated according to industry codes and standards. When dealing with breaks, cracks, holes, or any other type of pipe damage, the problem at hand would need to be carefully evaluated so that an approach that would minimize expenses and downtime could be devised.

Depending on the extent, severity, and localization of the damaged area, utility technicians would have to decide whether to shut down the line to replace the damaged section or perform on-line repair using different types of Smith and Blair repair clamps. In most cases, a combination of repair clamps and couplings provides the most practical and economical solution for industrial pipe repair.

What should you check before ordering a Smith-Blair repair clamp?

Before ordering a Smith-Blair repair clamp, confirm the pipe material, nominal size, outside diameter, pressure requirements, and type of damage. It is also important to note whether the issue is located along the pipe barrel, at a bell-and-spigot joint, or near a service connection, since different Smith-Blair products are designed for different repair needs.

If you are not sure which model fits the job, our team can help you compare available options in the Smith-Blair repair clamp catalog and determine whether a full-circle clamp, Redi clamp, bell joint leak clamp, service saddle, or coupling is the right fit.

What is a Smith-Blair pipe repair clamp used for?

Smith-Blair repair clamps are used to perform on-line repair of less severe cracks, pin-hole leaks, splits, punctures, and various other piping defects. There are different kinds of repair clamps used in industrial applications, including pin-hole leak repair clamps, encircling sleeves, “stand-off” pipe clamps, and more.

We offer a wide selection of repair clamps for all pipe sizes and configurations. Our range features clamps from many leading brands in the industry, including Hymax, Ford, Smith-Blair, and others.

What is the difference between a Smith-Blair clamp and a Smith-Blair coupling?

In cases of more extensive damage or deterioration of pipework, a Smith-Blair clamp may not be enough to resolve the problem. In such circumstances, the most economical and sensible solution is often to replace the affected section of pipe using a Smith-Blair repair coupling or other compatible pipe connectors.

The process typically involves cutting the damaged section and using two couplings to join the new length of pipe on both sides. This procedure requires the shutdown of the affected pipeline but offers several advantages, including deflection capabilities, easier maintenance, and increased shock absorption.

What pipe materials can Smith and Blair repair clamps be used on?

Smith-Blair clamps can be used on a range of pipe materials, depending on the specific model. For example, the Smith-Blair 226 is listed for materials such as ductile iron, cast iron, steel, copper, aluminum, PVC, HDPE, and more.

Other products may have more specific use cases. The Smith-Blair 274 Bell Joint Leak Clamp is designed for bell-and-spigot caulked or rubber ring joints on cast iron or ductile iron pipe, with certain PVC applications also listed when the proper requirements are met. Always match the product to the pipe material, OD range, pressure, and job conditions before installation.
