Legris 12 mm Push-Fit Plug

The Legris 3126 12 00 is a push-to-connect polymer plug designed to seal 12 mm outer diameter tubing in pneumatic systems. It suits maintenance engineers and installers who need a quick, tool-free way to blank off unused ports during assembly or service work. The black HAWA polymer body handles air service up to 290 psi and 176 Degrees F. Supplied in a pack of 10 pieces.

Installation ease and common issues

Push the plug straight into the fitting until it seats; the internal collet grips the tube automatically without tools. Removal requires pressing the release collar while pulling the plug out. The most frequent problem is an incomplete insertion that leaves a leak path, so verify the plug bottoms out at the 45 mm overall length. No thread sealant is included or required for this push-fit design.

Pre-order checks

Confirm the tubing outer diameter is exactly 12 mm and that the system pressure never exceeds 290 psi. Ensure the media temperature stays within the 176 Degrees F limit for the polymer material. The fitting complies with RoHS, REACH, PED and ISO 14743 standards, so verify these approvals satisfy any project specifications. This plug is not for buyers who need a threaded or barbed connection type.

Questions about this item

The pack contains ten black polymer plugs, each 45 mm long, pre-lubricated for push-to-connect fit; no separate thread sealant or special tools are required.

Which version should I choose for a 12 mm air line rated at 290 psi?

Select the 3126 12 00 model — it matches a 12 mm outer-diameter tube, 290 psi maximum pressure and 176 °F temperature limit.
