Parker 228-4-2 Barbed Tube Gauge Tee 1/8-27 Brass

Product Description

The PARKER 228-4-2 is a barbed tube gauge tee fitting designed to branch a pressure gauge port off an existing tubing line without interrupting flow. Constructed from brass, this fitting features multiple barbs for secure hose or tube retention and a 1/8-27 threaded gauge port. With a tube inside diameter of 0.17 inches, it is sized for small-bore tubing commonly found in pneumatic, hydraulic, and instrumentation systems. Installation is straightforward and is typically performed by licensed plumbers, HVAC technicians, or pipefitters working on low-pressure fluid or gas monitoring circuits.

This gauge tee is suited for residential and light commercial applications where an inline pressure tap is needed without cutting into a main line. Typical use cases include adding a gauge port to a compressed air line, refrigeration service connection, or fluid monitoring circuit. The brass body handles a wide range of compatible media and resists corrosion in most common service environments. Its compact form factor makes it practical in tight equipment enclosures or panel-mounted assemblies.

Key Features

• Brass construction for corrosion resistance and durability in fluid and gas service
• 1/8-27 threaded gauge port accommodates standard instrument connections
• Tube inside diameter of 0.17 inches for small-bore tubing applications
• Multiple barbs provide secure grip and reduce pull-out risk without clamps
• Compact tee design allows gauge branch without interrupting main flow path

Compatibility

Designed as an OEM-style replacement or direct-install barbed tube gauge tee for small-bore tubing systems using 1/8-27 threaded gauge ports.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or HVAC technician. Depressurize and isolate the line completely before removing or installing any fitting. Ensure barbed connections are fully seated and secure before returning the system to service. Follow applicable local codes and manufacturer torque guidance for threaded brass fittings.
