Air Line Stem Y Union Push-to-Connect Fittings – GPYJ Series


Advanced Pneumatic One-Touch Branch Connectors

The GPYJ Series of Air Line Stem Y Union Push-to-Connect Fittings provides a compact, versatile way to join or branch pneumatic tubing using a single stem inlet and twin push-fit outlets.

Designed for Nylon and Polyurethane tubing, these one-touch push-fit connectors enable instant, tool-free installation and removal, delivering leak-free performance and quick assembly in pneumatic and vacuum systems.

Available in stem and metric tube sizes 4 mm, 6 mm, 8 mm, 10 mm and 12 mm, in both equal and reducing configurations, the GPYJ range is ideal for branching air lines from a single feed with minimum space and weight.

Precision Metal & Resin Construction

Each fitting features a nickel-plated brass and resin body for strength and corrosion resistance, with NBR sealing rings, stainless-steel lock claws, and a POM sleeve + lock ring for dependable operation.
The zinc-alloy collet provides firm tube grip with smooth release, maintaining a consistent seal even under vibration or repeated use.
