Parker 712263 Steel Flared Tube Cap 7/8 in 37 Degree Flare

Product Description

The PARKER 712263 is a steel flared tube cap designed to seal the open end of a flared tube fitting. It features a 37-degree flare seat and fits a 7/8 inch tube outside diameter. Rated for a maximum working pressure of 5000 psi, this cap provides a reliable, pressure-tight closure on hydraulic and refrigeration lines during service, testing, or system decommissioning. The all-steel construction offers durability in demanding industrial and mechanical environments. Licensed HVAC technicians, plumbers, and pipefitters use this type of cap when isolating or capping off active or inactive flared tubing connections.

This cap is suited for use in hydraulic systems, refrigeration circuits, and high-pressure fluid lines where a flared tube end must be sealed. It is appropriate for both residential and light commercial applications wherever 37-degree flare fittings are standard. The 7/8 inch tube OD size is common in refrigerant line sets and hydraulic tubing runs. This item is sold in a package quantity of two.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or pipefitter familiar with flared tube fittings. Depressurize and isolate the system before removing or capping any fitting. Thread the cap onto the flare fitting by hand first, then tighten with an appropriately sized flare nut wrench to avoid cross-threading or deforming the flare seat. Follow all applicable local codes and system manufacturer procedures when capping active refrigerant or hydraulic lines.
