Cejn 10 430 5454 Pneumatic Hose Coupling 3/8 Mnpt

Product Description

The CEJN 10 430 5454 is a steel high-flow pneumatic hose coupling connector designed for use in compressed-air systems requiring reliable, leak-free connections. Built to the Industrial Interchange standard, this Series 430 connector features a 3/8-inch MNPT threaded connection and a 3/8-inch body diameter. It carries a maximum working pressure of 232 psi and handles temperatures from -4 degrees F to 212 degrees F, making it suitable for a broad range of shop-air and production-line environments. A zinc finish provides corrosion resistance for everyday industrial use. Licensed HVAC techs, plumbers, machinists, and general maintenance professionals rely on fittings like this for quick, secure pneumatic tool and hose connections.

This coupling is intended for compressed-air distribution systems using Industrial Interchange-style quick-connect fittings. It threads directly into air headers, manifolds, hose assemblies, or pneumatic tool ports using standard NPT pipe threads. The 3/8-inch sizing suits mid-range air tools and hose lines common in residential, commercial, and light industrial service settings. Its high-flow connector design helps minimize pressure drop across the fitting, which is useful when running demand-sensitive tools or equipment.

Key Features

• Industrial Interchange coupling type for broad cross-brand compatibility with matching quick-connect bodies
• 3/8-inch MNPT threaded connection for standard NPT pipe fittings and ports
• Maximum working pressure of 232 psi for demanding compressed-air applications
• Operating temperature range of -4 degrees F to 212 degrees F
• Steel construction with zinc finish for durability and corrosion resistance
• High-flow Series 430 design reduces pressure drop at the connection point

Compatibility

Designed as an OEM-style replacement or new-installation connector for compressed-air systems using Industrial Interchange standard quick-connect couplings with 3/8-inch NPT threaded ports.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or qualified maintenance technicians working on compressed-air systems. Depressurize and lock out the air supply before removing or installing any pneumatic fittings. Apply thread sealant tape or compound rated for compressed air to the MNPT threads before making up the connection. Tighten to hand-snug plus wrench-tight using an appropriately sized wrench — do not over-torque steel NPT fittings into softer port materials.
