Aignep Usa 88130-04 Union Elbow Tube Fitting 1/4 in Od

Product Description

The AIGNEP USA 88130-04 is a push-to-connect union elbow tube fitting designed for tube-to-tube connections in pneumatic and fluid-handling systems. Constructed from nickel-plated brass with a Buna O-ring, it delivers a rated maximum working pressure of 250 psi across a temperature range of -4 degrees F to 160 degrees F. The elbow configuration allows a direction change within a tubing run without additional fittings or adapters. Installation requires no tools for the tube connection itself, making it well suited for technicians assembling or servicing compressed-air, HVAC control-line, or light fluid-transfer plumbing where space and speed of assembly matter.

This fitting is intended for use with 1/4 inch OD tubing in tube-to-tube union elbow applications. It is commonly found in commercial and residential HVAC control systems, pneumatic instrumentation lines, and light industrial fluid-handling assemblies. The push-to-connect design allows for fast field assembly and, when needed, straightforward disassembly for service or reconfiguration. It is typically installed by HVAC technicians, plumbers, or instrumentation mechanics working with small-diameter pneumatic or low-pressure fluid lines.

Key Features

• Push-to-connect design allows tool-free tube insertion and secure hold at 250 psi maximum working pressure
• Nickel-plated brass body resists corrosion in typical HVAC and pneumatic environments
• Buna O-ring provides reliable sealing across the full operating temperature range
• Union elbow configuration enables a 90-degree direction change in a single fitting
• Rated from -4 degrees F to 160 degrees F for broad application coverage
• Compliant with REACH, RoHS, ISO 14743:2004, and PED 2014/68/UE standards

Compatibility

Designed for use with 1/4 inch OD tubing in tube-to-tube union elbow push-to-connect applications across pneumatic and fluid-handling systems.

Installation Notes

De-pressurize and isolate the tubing circuit fully before removing or installing any push-to-connect fitting. Cut tubing squarely and deburr the end before insertion to ensure proper seating and sealing against the O-ring. Verify that tubing OD matches the fitting specification before assembly. This fitting should be installed by a qualified technician familiar with applicable pneumatic or plumbing system codes.
