Air Line Bulkhead Union Push-to-Connect Fittings – GPM Series
Advanced Pneumatic One-Touch Panel-Mount Connectors
The GPM Series of Air Line Bulkhead Union Push-to-Connect Fittings provides a secure, leak-free way to connect Nylon and Polyurethane tubing through panels or enclosures.
Featuring a one-touch push-fit design, the GPM range allows instant tube connection and release — ideal for pneumatic and vacuum systems where space and accessibility are limited.
Available in metric tube sizes 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, and 16mm, each model includes a threaded bulkhead section and locknut for easy panel mounting.
Precision Metal Construction
Manufactured from nickel-plated brass for corrosion resistance and strength, these fittings incorporate NBR sealing rings, stainless-steel lock claws, and a POM sleeve and lock ring for secure tube retention.
The zinc-alloy collet ensures firm grip and quick release, maintaining a reliable seal under vibration and repeated use.
Panel Mount Thread Sizes
Models use metric mounting threads from M12x1 to M26x1, with overall body lengths between 29.5 mm and 51 mm depending on size — suitable for most control panels, manifolds, and equipment housings.
