Parker 712261 Steel Flared Tube Cap 5/8 in 37 Degree

Product Description

The PARKER 712261 is a steel flared tube cap designed to seal the open end of a flared tube line in hydraulic, pneumatic, or fluid-transfer systems. Featuring a 37-degree flare end connection and a 5/8 inch tube outside diameter, this cap provides a secure, pressure-rated closure rated to 5000 psi maximum working pressure. It is built from steel for durability in demanding service environments and is rated for temperatures up to 500 degrees F. Licensed plumbers, hydraulic technicians, and fluid-system assemblers use this fitting to cap off unused or temporarily inactive line ends during system maintenance, testing, or phased installation work.

This cap is suited for use in industrial fluid-transfer systems, hydraulic lines, and related plumbing assemblies where a 37-degree JIC-style flare connection is the standard end type. It is a practical solution for capping 5/8 inch OD tube ends in both commercial and light-industrial applications. The package contains 2 pieces per unit, making it efficient for jobs requiring multiple capped terminations on a single system or across multiple circuits.

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid-transfer systems using 37-degree JIC flare connections with 5/8 inch OD tubing.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with flared tube fittings. Depressurize and isolate the system completely before removing any existing fittings or installing this cap. Inspect the mating flare seat for damage or debris before assembly to ensure a proper seal. Follow SAE J514 assembly guidelines for appropriate tightening procedures on JIC flare connections.
