Parker PT-00261 Brass Male Adapter 1/2 in 3/8-18 Nptf 37 Flare

Product Description

The PARKER PT-00261 is a brass flared tube male adapter designed for use in hydraulic, refrigeration, and fluid-transfer line assemblies. It features a 37-degree flare end that mates with standard JIC-style flared tubing on one side and a 3/8-18 NPTF male thread on the other, creating a leak-resistant metal-to-metal seal. The outside diameter of the tube end is 1/2 inch, and the overall length is 1.53 inches. At a maximum dynamic working pressure of 3,300 psi, this fitting is suited for high-pressure service lines. The brass construction provides corrosion resistance in air, water, and many hydraulic fluid environments. Licensed HVAC technicians, plumbers, and fluid-power mechanics are the typical installers.

This adapter is commonly used to transition from a flared tube run to a threaded port on valves, manifolds, pumps, or equipment housings. It fits residential and light commercial refrigeration systems, hydraulic equipment, and pneumatic plumbing wherever a 37-degree SAE flare-to-NPTF male connection is required. Each package contains 5 pieces, making it practical for service vans and shop stock. It meets ISO 8434-2, SAE J514, and SAE 070102 standards, confirming suitability across a broad range of system types that specify these flare fitting standards.

Key Features

• 37-degree flare end conforms to SAE J514 for reliable metal-to-metal sealing
• 3/8-18 NPTF male thread provides a dry-seal connection without sealant tape when torqued properly
• Maximum dynamic working pressure of 3,300 psi suitable for high-pressure hydraulic and refrigerant lines
• Brass construction resists corrosion in water, air, and common hydraulic and refrigerant fluid media
• Compact overall length of 1.53 inches for use in tight routing configurations
• Sold in a 5-piece package for convenient shop or field restocking

Compatibility

Designed as an OEM-style replacement or service fitting for systems specifying a 37-degree SAE flare by NPTF male adapter with 1/2 inch tube OD and 3/8-18 thread, conforming to ISO 8434-2, SAE J514, and SAE 070102 standards.

Installation Notes

Installation should be performed by a qualified mechanic or licensed technician familiar with flared tube fittings and NPTF threaded connections. De-energize and depressurize the system fully before disconnecting or installing any fitting. Inspect the flare seat and tube flare for nicks or deformation before assembly, as damaged seating surfaces will prevent a proper metal-to-metal seal. NPTF threads are designed for dry-seal engagement, but consult the system manufacturer guidelines for any required thread sealant use.
