Parker PT-00323 Stainless Steel Flared Tube Cap 1/2 in Od

Product Description

The PARKER PT-00323 is a stainless steel flared tube cap designed to seal the end of a 1/2 inch OD flared tube line. The 37-degree flare end connection conforms to SAE J514 and ISO 8434-2 standards, making it suitable for high-pressure hydraulic, pneumatic, and fluid system applications. This cap handles working pressures up to 6000 psi static and 7200 psi dynamic, with a temperature range spanning from -425 degrees F to 1200 degrees F. Plumbers, hydraulic system technicians, and HVAC mechanics install this fitting wherever a flared tube end must be capped, isolated, or temporarily sealed during service or system modification.

This fitting is used in residential and commercial installations where stainless steel corrosion resistance is required. Common applications include refrigeration line sets, hydraulic circuits, fuel systems, and instrumentation tubing. The 37-degree flare profile ensures a metal-to-metal seat that maintains integrity under high-pressure dynamic loads. Each package contains 2 caps, making it practical for field service kits and job-site repairs where spares are routinely kept on hand.

Compatibility

Designed as an OEM-style replacement or service fitting for 1/2 inch OD flared tube lines using a 37-degree SAE flare connection in hydraulic, pneumatic, refrigeration, or instrumentation systems.

Installation Notes

Installation should be performed by a qualified technician familiar with high-pressure fluid or refrigeration systems. Depressurize and isolate the line completely before removing any existing fitting or installing this cap. Inspect the flare seat for nicks or damage before seating the cap, as metal-to-metal flare connections depend on clean seating surfaces for a proper seal. Torque to the fitting manufacturer specifications per SAE J514 guidelines for the applicable tube size and material.
