Parker PT-00320 Stainless Steel Flared Tube Cap 1/4 in

Product Description

The PARKER PT-00320 is a stainless steel flared tube cap designed to seal the end of a 1/4-inch OD flare fitting. It uses a 37-degree flare end connection conforming to SAE J514 and ISO 8434-2 standards. The cap terminates open flare lines in hydraulic, pneumatic, and fluid-transfer systems where a pressure-rated closure is required. It handles maximum working pressures up to 7,500 psi static and 9,000 psi dynamic, with a temperature range from -425 degrees F to 1,200 degrees F. Stainless steel construction makes it suitable for corrosive-fluid and high-temperature service environments. Licensed trades including plumbers, HVAC technicians, and hydraulic system technicians install this fitting type during system maintenance, line isolation, and pressure testing.

This cap fits 1/4-inch OD flared tubing lines in residential, commercial, and industrial applications. Typical use cases include capping unused ports on manifolds, sealing decommissioned branch lines, and blanking off flare connections during system modifications. The 37-degree JIC-style flare interface is standard across hydraulic control circuits, refrigeration lines, and instrumentation tubing. Each package contains 2 caps.

Compatibility

Designed as an OEM-style replacement or service fitting for 1/4-inch OD 37-degree flare tube assemblies meeting SAE J514 and ISO 8434-2 specifications.

Installation Notes

Installation is performed by qualified plumbers, HVAC technicians, or hydraulic system technicians. Depressurize and isolate the affected line completely before removing any existing fitting or installing this cap. Inspect the mating flare seat for nicks or deformation before seating the cap; a damaged seat will prevent a leak-free seal. Follow applicable system pressure-test procedures and relevant codes after installation to confirm integrity.
