The PRO-SOURCE 2555551365PRO is a push-to-connect tube-to-universal-thread fitting designed for fast, tool-free tube connections in compressed air and water systems. Constructed from nickel-plated brass, this fitting accepts 5/16 inch OD tubing and features a 3/8 inch universal thread on the mating end. It is rated to 250 psi, making it suitable for standard compressed air distribution and plumbing lines. The push-to-connect mechanism allows a technician to seat the tube with a single push and release it by depressing the collet. Plumbers, pipefitters, and HVAC-R technicians working on pneumatic controls, air lines, or water supply connections are the primary installers.
This fitting is used in residential and light commercial applications where a reliable push-to-connect interface is needed between flexible tubing and a threaded port. Typical scenarios include compressed air tool lines, pneumatic control systems, and potable or process water circuits. The universal thread end provides flexibility when connecting to a variety of threaded ports without requiring specialized adapters. Each package contains 5 fittings, allowing technicians to stock multiple connection points from a single order.
Designed for use with compressed air and water systems requiring a 5/16 inch OD tube and a 3/8 inch universal thread port connection.
Installation is performed by plumbers, pipefitters, or HVAC-R technicians. Before installing or removing this fitting, depressurize and isolate the line completely. Ensure the tube end is cut cleanly and squarely with a tube cutter to achieve a proper seal at the collet. To remove the tube, depress the collet ring evenly while pulling the tube straight out.
