Parker 270AB-4-2 Compression Female Elbow 1/4in Od Brass

Product Description

The PARKER 270AB-4-2 is a brass compression tube female elbow fitting designed to connect 1/4-inch OD tubing to a 1/8-27 NPTF female threaded port at a 90-degree angle. It provides a reliable, leak-resistant compression-to-FNPT transition in fluid and pneumatic lines. Rated to 400 psi maximum working pressure and a temperature range of -65 to 250 degrees F, this fitting suits demanding service environments. Licensed plumbers, HVAC technicians, and pneumatic system installers use this fitting when routing tubing into a female NPT port where an inline connection is not practical. Compliance with D.O.T. FMVSS571.106 and SAE J246 confirms it meets recognized performance standards for tube fittings.

This fitting is suited for residential and light commercial plumbing, pneumatic control lines, refrigeration sensing lines, and hydraulic instrumentation applications where a 1/4-inch OD compression tube must terminate at a 1/8-27 FNPT port. The elbow configuration allows routing tubing at a right angle to the port face, reducing stress on the tubing in tight spaces. It is sold individually and is appropriate for both new installation and repair or replacement work on existing systems.

Key Features

• Brass construction provides corrosion resistance and durability in fluid and pneumatic service
• Compression x FNPT end connections allow tool-free tube attachment with a standard compression nut and ferrule
• 400 psi maximum working pressure rating for reliable performance in pressurized systems
• Wide temperature range of -65 to 250 degrees F supports refrigeration, HVAC, and pneumatic applications
• Meets D.O.T. FMVSS571.106 and SAE J246 standards for tube fitting performance and safety
• 1/8-27 NPTF thread standard ensures tight, pressure-rated thread engagement at the female port

Compatibility

Designed as an OEM-style compression tube fitting for use with 1/4-inch OD tubing connecting to 1/8-27 FNPT ports in plumbing, pneumatic, HVAC, and fluid instrumentation systems.

Installation Notes

Installation is performed by a licensed plumber, HVAC technician, or qualified pneumatic systems technician. Shut off and depressurize the system completely before disconnecting or installing any fitting. Thread the FNPT end into the mating port to the appropriate engagement depth without over-tightening brass threads; use thread sealant appropriate for the service fluid. Insert the tubing into the compression end, tighten the compression nut finger-tight, then advance with a wrench per standard compression fitting practice — do not over-torque.
