Parker 712259 Steel Flared Tube Cap 3/8 in 37 Degree

Product Description

The PARKER 712259 is a steel flared tube cap designed to seal the open end of a 3/8-inch OD flare fitting. It uses a 37-degree flare end connection, conforming to SAE J514 and ISO 8434-2 standards. Rated to 6000 psi maximum working pressure and a maximum working temperature of 500 degrees F, this cap is built for demanding hydraulic and fluid system applications. Licensed plumbers, hydraulic system technicians, and pipefitters install this type of fitting when capping off active or inactive lines during service, system modification, or pressure testing.

This cap is suited for use in hydraulic lines, fluid power systems, and high-pressure tubing assemblies where a reliable, pressure-rated seal is required. The 37-degree flare geometry is standard in JIC-style hydraulic fittings commonly found in industrial, mobile equipment, and HVAC refrigerant line applications. It is sold in a package quantity of 5 units.
