Parker 270AB-8-6 Compression Female Elbow 3/8-18 Brass

Product Description

The PARKER 270AB-8-6 is a brass compression tube female elbow fitting designed to connect tubing to female NPT threaded ports at a 90-degree angle. It uses a compression-style tube end on one side and a 3/8-18 FNPT connection on the other, making it suitable for fluid and pneumatic line routing where a direction change is required. Rated to 400 psi maximum working pressure, the fitting handles temperatures from -65 degrees F to 250 degrees F. It meets D.O.T. FMVSS571.106 and SAE J246 standards, making it appropriate for brake and hydraulic line applications in both mobile and stationary equipment. Licensed plumbers, HVAC technicians, and fluid power specialists are the typical installers.

This fitting is used in hydraulic, pneumatic, and fluid transfer systems where tubing must transition to a female NPT threaded port at a right angle. Its brass construction suits water, air, and compatible hydraulic fluid service. The compression end allows for a tool-assisted, leak-resistant connection without soldering or flaring, which is practical for field repairs and new installations alike. It is well suited to residential and light commercial HVAC refrigerant line accessories, compressed air systems, fuel lines, and DOT-regulated brake tubing assemblies.

Key Features

• Compression x FNPT end connections for direction change in tubing runs
• 3/8-18 NPTF thread standard for reliable pressure-tight engagement
• 400 psi maximum working pressure rating
• Operating temperature range: -65 degrees F to 250 degrees F
• Meets D.O.T. FMVSS571.106 and SAE J246 standards
• Brass construction for corrosion resistance and machinability

Compatibility

Designed as an OEM-style replacement or service fitting for compression tube to female NPT elbow applications in DOT-compliant and general fluid power systems where 3/8-18 NPTF thread and compression tube connections are specified.

Installation Notes

Installation should be performed by a qualified technician familiar with compression fitting assembly and applicable fluid system codes. Depressurize and isolate the system completely before disconnecting or installing any fitting. Compression fittings require the tube end to be cut squarely and deburred before insertion; do not over-tighten the compression nut, as brass fittings are susceptible to thread damage. Verify thread compatibility with the mating port before assembly, as NPTF and NPT threads differ in sealing behavior under pressure.
