Parker PT-00317 Steel Flared Tube Cap 1/8 Inch Od 37 Degree

Product Description

The PARKER PT-00317 is a steel flared tube cap designed to seal the end of a flared hydraulic or fluid line with a 37-degree flare angle. It accepts a tube with a 0.125-inch outside diameter and is rated for a maximum working pressure of 7,500 psi and a maximum working temperature of 500 degrees F (260 degrees C). The cap uses a flare-end connection conforming to ISO 8434-2, SAE 070112A, and SAE J514 standards. It is a compact fitting with an overall length of 0.6 inches and weighs approximately 0.01 pounds. Licensed tradespeople in hydraulics, plumbing, and HVAC install this fitting to cap off unused or temporarily decommissioned fluid lines.

This tube cap is appropriate for use in high-pressure hydraulic systems, refrigeration lines, fuel systems, and instrumentation tubing where a secure, leak-free termination of a 1/8-inch OD flared line is required. Its steel construction and conformance to SAE J514 make it suitable for both industrial and mobile equipment applications. Typical scenarios include capping a branch port during system commissioning or isolating a circuit during maintenance. Sold in packages of 5.

Installation Notes

Installation should be performed by a qualified technician familiar with high-pressure fluid system procedures. Before installing or removing any fitting, depressurize and isolate the affected circuit completely. Inspect the flare seat on the tube end for nicks or damage before seating the cap, as a compromised flare surface can cause leaks under pressure. Follow applicable SAE and system-specific torque and assembly guidelines for 37-degree flare fittings.
