Parker 36990420 Push-to-connect Tube Fitting 10-32 Unf

Product Description

The PARKER 36990420 is a push-to-connect tube-to-male tube-to-male UNF fitting designed for quick, tool-free connections in pneumatic and fluid-handling systems. Constructed from nickel-plated brass, this fitting handles a maximum working pressure of 435 psi and is rated for use with both liquid and gas media. The FKM O-ring provides reliable sealing across a wide range of fluids and temperatures. It accepts 5/32-inch OD tubing and threads into a 10-32 UNF male port, making it a compact solution for tight plumbing runs. Licensed plumbers, HVAC technicians, and industrial maintenance techs install this fitting when routing small-bore tubing in instrumentation, controls, and pneumatic circuits.

This fitting is suited for residential and light commercial applications where small-diameter tubing connects to threaded male ports. Typical install scenarios include pneumatic control lines, instrument sensing lines, and low-pressure fluid transfer circuits. The tube-to-male tube-to-male configuration allows an inline connection between a threaded port and a push-to-connect tube run, reducing the number of fittings needed in a system. It is compatible with both liquid and gas service, giving technicians flexibility across a range of equipment types.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and removal
• Nickel-plated brass body resists corrosion in liquid and gas service
• FKM O-ring provides a broad chemical compatibility seal
• Rated to 435 psi maximum working pressure
• 10-32 UNF thread for precise engagement with standard male ports
• Accepts 5/32-inch OD tubing for small-bore pneumatic and instrumentation lines

Compatibility

Designed for use with liquid and gas media in systems requiring 5/32-inch OD tubing and a 10-32 UNF threaded male port connection. Suitable as a direct replacement fitting in pneumatic controls, instrumentation lines, and similar small-bore fluid systems.

Installation Notes

This fitting is typically installed by licensed HVAC technicians, plumbers, or instrumentation technicians. Before installation, isolate and depressurize the system completely and verify that tubing OD and thread engagement meet the fitting specifications. Ensure tubing is cut cleanly and squarely before inserting into the push-to-connect port to achieve a proper seal. Refer to applicable system codes and the equipment manufacturer guidelines for torque and assembly requirements on the threaded male port.
