Unlike unshielded couplings, shielded ones are made with high-torque clamps, a gasket, and a heavy-duty shear ring which is meant to help the pipeline withstand shear forces and tensile stressing as well as keep pipe alignment. While this coupling is typically used underground, it can also be effective in above-ground applications.

Pipeline failure can be extremely dangerous, so it’s of the utmost importance to use the right type of coupling that is of high quality. Keep reading to explore 7 different types and find out where to get Fernco shielded and flexible couplings as well as clamps in Watertown.

What are the main variants of shielded repair couplings?

Shielded couplings differ based on their features, application, benefits, size, etc. Before purchasing them, you should get familiar with different types to know exactly which ones you need. Here are 7 types you can choose from:

Stainless steel shear rings

Stainless steel shear rings are used to maintain good alignment even in bad conditions. They’re usually sold as 1-1/2″ to 15″ couplings and even custom-sized. Their highest operating temperature is 140° F. Their accessories include a 5/16″ ratchet torque wrench – TW100 and TW200. The installation is fast and simple.

No-hub couplings

These couplings are manufactured to connect no-hub cast iron pipes. A no-hub coupling contains a patented shield design providing maximum pressure transfer from the clamps to the gasket and pipe. It comes in different sizes and designs, such as:

• Patented bi-directional shield design
• Specially beaded gasket
• Interlocking clamp design
• Floating eyelet design

Proflex couplings

These are specialty couplings engineered to resist shear forces. They’re shielded transition couplings made to allow safe and long-lasting pipe connections. The Proflex couplings are effective for steel, iron, copper, plastic vent, and drain waste above-ground systems. Their maximum operating temperature is 180° F.

XL couplings

XL couplings are built for extreme conditions, so they’re extra long, more durable, and stronger than most couplings. They’re equipped with two clamps.

HTRC corrugated pipe flexible couplings

As their name states, they’re used on corrugated pipes. They provide greater sealing force and are extremely effective for stormwater and gravity-flow sewer systems. Some of their features include shear resistance, pipe alignment, high-torque clamps, and smooth sealing gasket.

Strong-back RC 5000 series couplings

These couplings provide excellent pipe alignment and help resist shear forces and heavy earth loads. They have a stainless steel shield and clamps. Their highest operating temperature is 140° F.

Chemical couplings

As they have clamping and a shear band enclosing a high-performance elastomeric sleeve with a chemically resistant one-piece Fluoropolymer (FEP) liner and PTFE seals, chemical couplings are made to withstand a wide variety of chemicals. They’re flexible and provide reliable pipe connections on drainage systems. They’re effective for both under and above-ground applications. The maximum temperature they can operate under is 266° F intermittent and 212° F consistent.
