What is a push lock fitting?

Push-lock hose fittings (aka push-lok, push-on, insta-grip and field attachable fittings) lets technicians attach connectors and fittings to hoses in the field for low-pressure hydraulic and pneumatic systems such as shop air, general industrial, maintenance and automotive assembly, to name a few.

Do push lock fittings need clamps?

The fittings are designed to be used without clamps but nobody will blame you if you put clamps on them. I used push lock on our entire oil system before I switched to dry sump with no problems. I use them on all my fuel lines as well.

Are push lock fittings reusable?

What’s more, Push-Lok fittings are reusable. Just replace the hose at the job site without any special tools or clamps. Helping you maintain a clean environment on the job is another important reason to use Parker’s Push-Lok system.

How do you tell what size an fitting I have?

You can always identify AN fittings based on the male thread size (outside diameter). These sizes are constant regardless of brand, hose type, or fitting configuration. If your fitting has a convex 37 degree flare at the end, the threads will tell you the AN size (and vice-versa).

How much pressure can a push lock fitting take?

This type of assembly can typically handle pressures of up to roughly 24 bar (350 psi), depending on the hose’s capabilities. As a result, the vast majority of hydraulic systems cannot utilise push-lock fittings.

How do push fittings work?

The fittings are engineered with a ring of metal spurs inside the fittings that tightly grip the pipes when they are inserted into the fitting sockets. When you are making joints for CPVC, PEX, or copper pipes, push-fit fittings are by far the quickest and easiest way to go.
