The 3/8 in. Stem x 3/8 in. Hose Barb Plastic Adapter is a plastic push-in (stem-type) hose barb adapter for low-pressure pneumatic control circuits, instrument air lines, and light fluid transfer systems. The push-in collet or barbed stem grips tubing with a single push; a wrench-tight male NPT thread connects to equipment ports. Plastic construction reduces weight and cost versus brass fittings in applications where corrosion resistance of the wetted path is more important than high pressure ratings.

Key Features
- Lightweight plastic body — cost-effective for high-quantity pneumatic panel builds
- Push-in collet or stem grips tubing securely at rated working pressure
- Chemical resistance to water, dilute acids, and most non-halogenated gases
- Male NPT thread for direct installation into standard port sizes
- Use in low-pressure air, instrument gas, and light water service only
Common Applications
Pneumatic solenoid valve manifolds, instrument air control panels, RO system water distribution, light chemical dosing secondary lines, and any low-pressure pneumatic or fluid circuit where brass push-to-connect cost is a factor.
