Why Choose Push-Fit Fittings From John Guest
For crews focused on speed and reliability, push-to-connect fittings transform how lines are assembled. They pair straightforward assembly with trusted sealing technology so crews use less time per connection.
Fast, Easy, Tool-Free Installs That Lock Securely
With Speedfit and ProLock, quick easy assembly can trim installation time by up to about 40%. The design grips tubing and pipes with low insertion force and a dependable lock.

Twist-And-Lock Plus Superseal Technologies To Limit Leaks
Twist-and-lock versions boost retention in areas where vibration or movement is common. Superseal incorporates double O-ring seals, making leaks much less likely.
ProLock is suitable for hot water and cold water in sizes from 3/8″ to 1″ and handles higher pressure well. Speedfit and ProLock are not rated for gas, fuel oil, or compressed air service.
| Product line | Best Use | Key Feature | Typical Size |
|---|---|---|---|
| Speedfit | Fast potable runs | Push-to-connect seal for plastic/copper | 1/4″–3/4″ |
| ProLock | Hot water plus higher-pressure lines | Strong lock with high-temperature resilience | 3/8″–1″ |

Installation Tips For Secure, Push-Fit Connections
With a few small prep steps, push-fit connections can perform like pro-grade joints. Installation Parts Supply suggests several consistent actions that reduce leaks and callbacks. Follow simple habits to keep assembly quick easy and reliable on every run.
Cutting Square Ends, Seating Fully, And Adding Locking Clips
Cut the tube square, then deburr the end so the O-ring seats evenly. A rough or angled cut can damage seals and cause leaks.
Mark the proper insertion depth and push in until the tube seats fully. Verify by pulling back gently, then add a lock clip on critical joints for added retention.
When To Use Twist-And-Lock Or Superseal
In areas with vibration or movement, choose twist-and-lock connections. It boosts retention without sacrificing quick easy assembly.
Select Superseal for double O-ring protection near equipment or service-critical spots. Use tube supports on soft tubing and hot water lines to keep sealing pressure consistent.
“Cut square, push fully home, and lock with clips—these steps save time and future service calls.”
- Reduce stress on pipe and fittings by avoiding side-loads and supporting long spans.
- Always keep parts free of debris; contamination can compromise seals and increase leak risk.
- Reference full details and view the rated temperature and pressure before using any fitting.
- Carry spare clips and release tools for quick field adjustments.
