Ford Compression Fittings vs. Grip Joint: Which One Should You Use?

What’s the difference between a compression fitting and a grip joint

If you’re a professional working on water service lines or municipal connections, chances are you’ve come across both Ford compression fittings and grip joints. While they are similar in appearance and purpose, these connectors work a little differently.

However, in critical infrastructures, a “little differently” can make a massive difference. This is why it’s imperative to know which one to use and when, as this can save you time, money, and a whole lot of headaches in the future.

Are compression fittings better than grip jointsWhat’s the difference between a compression fitting and a grip joint?

At first glance, it may seem that there’s no difference between the two connectors. At the core, grip joints and compression fittings serve the (almost) exact same purpose: to create a strong, lasting, and leak-free connection between two pipes. However, they achieve these goals in specific ways:

  • Compression fittings use a tightening nut and internal ferrule to create a watertight seal around the pipe. When properly installed, the fitting compresses the pipe evenly, providing a strong mechanical grip and leak-free connection. These connectors are most commonly used for copper and polyethylene (PE) pipe connections.
  • Grip joint fittings, on the other hand, feature a segmented stainless-steel ring that literally “grips” the outside of the pipe as you tighten the nut. This added mechanical restraint is particularly useful for high-pressure applications or where pipe pullout resistance is critical, which is why these connectors are often used in directional boring or where thrust blocking isn’t feasible.

Are compression fittings better than grip joints?

As shown above, whether one is better than the other depends wholly on the specific job objectives. For instance, if you’re working with poly pipe in a trench or low-pressure service, compression fittings are often sufficient and easier to install quickly.

However, if you’re installing pipe in an area with unusual movement risk, deeper mains, or no thrust blocks, grip joint fittings provide extra security that compression fittings just can’t match. Of course, we can’t cover every scenario, so here’s a next best thing: a quick comparison chart to help guide your decision.

Feature Compression Fitting Grip Joint Fitting
Best for Standard water service lines High-pressure or high-risk pipe movement areas
Pipe Types Copper, PE, HDPE PE, HDPE, Copper (with some adapters)
Restraint Relies on compression force only Built-in mechanical grip for added pipe restraint
Ease of Installation Very straightforward Slightly more prep but offers a stronger hold
Pullout Resistance Moderate High

One thing both these options have in common? They’re made with Ford’s signature reliability, so you can rest easy knowing that they are built to last and easy to work with.

On a final note, in addition to specific project specs, it’s imperative to check local codes and regulations. Some municipalities have strict requirements regarding materials in key infrastructures, and they may specify one type of fitting over another for certain applications.
