Parker PT-00265 Brass Male Adapter 1 in Od 1-11-1/2 Nptf 37 Flare

Product Description

The PARKER PT-00265 is a brass flared tube male adapter designed to transition a 37-degree flared tube end to a male NPTF threaded connection. Constructed from brass, it accepts a 1-inch tube outside diameter on the flare end and connects to a 1-11-1/2 NPTF thread on the male end. The 37-degree flare angle conforms to the SAE standard flare geometry widely used in hydraulic, refrigeration, and fluid-handling systems. This fitting is rated for a maximum dynamic working pressure of 2000 psi, making it appropriate for moderate-pressure service lines. Plumbers, HVAC technicians, and hydraulic system installers use this adapter where a flared tube line must terminate at a threaded port or valve body.

This adapter sees regular use in residential and commercial HVAC systems, refrigeration lines, hydraulic circuits, and plumbing applications where a flared copper or steel tube must interface with a female NPTF port. The NPTF thread form creates a dry-seal mechanical connection that does not rely solely on thread sealant for leak prevention, which is an advantage in higher-pressure or vibration-prone installations. Sold in a package quantity of 2, it suits both single-repair jobs and bench-stock replenishment for service vans.

Key Features

• 37-degree SAE flare end accepts 1-inch tube OD
• 1-11-1/2 NPTF male thread for dry-seal port connections
• Brass construction resists corrosion in fluid-handling environments
• Rated to 2000 psi maximum dynamic working pressure
• Package quantity of 2 per order unit

Compatibility

Designed as a standard SAE 37-degree flare-to-NPTF male adapter for hydraulic, HVAC, refrigeration, and plumbing tubing systems using 1-inch OD flared tube lines and 1-11-1/2 NPTF threaded ports.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or hydraulic systems technician familiar with flare fittings and NPTF thread standards. Depressurize and isolate the line completely before disassembly or fitting replacement. Inspect the flare seat and tube end for damage or out-of-round condition before tightening, as a compromised flare surface will not seal reliably. NPTF threads are designed for mechanical dry-seal engagement, but thread sealant or tape may still be applied per the system manufacturer or applicable code requirements.
