PUSH-IN FITTINGS

PUSH-IN FITTINGS

Push-in fittings by Metal Work are the best elements for connecting

pipes and actuators.

Quick and easy to use, the Metal Work push-in fitting can be re-used

thousands of times without affecting the pneumatic and mechanical

seal in any way. It comes in various configurations and guarantees

a virtually unlimited, highly flexible use. The clamping spring

with its special shape grips the pipe without scratching or deforming

it, which facilitates release.

In the fittings, the release bushing has patented screwdriver slots

to facilitate release in applications not accessible to the fingers.

Configurations RL19, RL21, RL22, RL23, RL23M, RL24, RL44,

and RL49 (except for Ø5), have a ring for fixing to the wall

asymmetrically in order to contain the head of a screw within

the overall dimensions of the fitting.
