Aignep Usa 88030-04-02 Push-to-connect Tube Fitting

Product Description

The AIGNEP USA 88030-04-02 is a straight push-to-connect tube fitting with a female NPT port, designed for inline connections in pneumatic and fluid-transfer lines. Constructed from nickel-plated brass, it accepts 1/4 inch OD tubing on each tube port and features a 1/8 inch NPTF female thread at the center port. The fitting is rated to 250 psi maximum working pressure and handles temperatures from -4 degrees F to 160 degrees F, making it suitable for a wide range of compressed-air and light fluid service applications. The Buna O-ring seal provides reliable, leak-resistant performance at the push-to-connect interface. Plumbers, HVAC technicians, and pneumatic system installers use this type of fitting to create fast, tool-free tube connections in tight spaces.

This fitting is suited for residential and commercial pneumatic systems, compressed-air distribution lines, and control-circuit tubing runs where a branch or inline female NPT port is needed alongside push-to-connect tube terminations. It is a common choice in HVAC controls, air-actuated valve assemblies, and small-bore fluid-handling panels where quick assembly and disassembly reduce service time. The straight configuration keeps routing simple in confined enclosures or manifold assemblies.

Compatibility

Designed as an OEM-style fitting for pneumatic and fluid-transfer systems using 1/4 inch OD tubing with 1/8 inch NPTF female ported connections.

Installation Notes

Installation is performed by pneumatic system technicians or plumbers working on compressed-air or fluid-control circuits. Depressurize and isolate the line completely before removing or installing any push-to-connect fitting. Apply an appropriate thread sealant to the NPTF threads in accordance with system requirements and applicable codes. Ensure the tube end is cut cleanly and squarely and is free of burrs before inserting into the push-to-connect port to achieve a proper seal.
