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.
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:
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.
