Parker 61PN-6 Compression Tube Nut Brass 150 Psi

Product Description

The PARKER 61PN-6 is a brass compression tube nut designed for use in compression-style tube fittings. It serves as the threaded fastening component that secures tubing within a compression fitting assembly, creating a leak-resistant mechanical connection without soldering or flaring. Constructed from brass, it offers good corrosion resistance and is suited for a range of fluid and gas line applications. The 61PN-6 is rated for a maximum working pressure of 150 psi and handles temperatures from 0 degrees F to 150 degrees F, making it appropriate for common plumbing and instrumentation installations handled by licensed plumbers and pipefitters.

This compression tube nut is used in residential and light commercial plumbing, HVAC refrigerant accessory lines, instrumentation tubing, and fluid handling systems where compression-style fittings are specified. It is typically installed in situations requiring a serviceable, re-torqueable connection on copper or compatible tubing. Licensed plumbers and mechanical contractors are the primary installers, though experienced trade technicians across HVAC and industrial service regularly work with components of this type.

Key Features

• Brass construction provides corrosion resistance suitable for water, air, and compatible fluid service
• Compression end connection eliminates the need for soldering, flaring, or adhesives
• Rated to 150 psi maximum working pressure
• Temperature range of 0 degrees F to 150 degrees F covers standard plumbing and HVAC accessory applications
• Threaded nut design allows for field assembly and future disassembly without special tooling

Compatibility

Designed as an OEM-style compression tube nut for use in standard compression fitting assemblies requiring a brass nut component of the corresponding tube size.

Installation Notes

Installation is typically performed by a licensed plumber or qualified mechanical technician. Shut off and depressurize the line before disassembling or installing any compression fitting component. Hand-tighten the nut first to seat the ferrule, then advance with a wrench per standard compression fitting practice — avoid overtightening, which can deform the ferrule and compromise the seal. Work should comply with applicable IPC or local plumbing code requirements.
