PU / PG Pneumatic Straight Connector – Equal & Reducing Push-In Fitting 4–16mm (50–1000PCS)
PU / PG Pneumatic Push-In Straight Connector – Equal & Reducing Fitting (4mm–16mm)
The PU (Equal) and PG (Reducing) Pneumatic Straight Connectors are high-performance push-to-connect air fittings designed for fast, secure and leak-resistant tube connections in compressed air systems.
Manufactured from durable PBT plastic material, these connectors support working pressure up to 1MPa and operate within a temperature range of 0–60°C, making them ideal for industrial automation, pneumatic control systems and air distribution lines.
Available in 4mm to 16mm outer diameter options, including both equal (PU) and reducing (PG) configurations, these fittings provide flexible installation for various tubing sizes.
Why Choose PU / PG Pneumatic Connectors?
Strong, impact-resistant plastic body for long service life.
Reliable performance in compressed air systems.
Tool-free installation saves time and labor.
PU = same diameter connection
PG = different diameter reduction
4mm / 6mm / 8mm / 10mm / 12mm / 14mm / 16mm
Available in 50 / 100 / 500 / 1000 PCS bulk options.
