Parker MP11044 Compression Tube Nut 1/2 in Od Brass 10-pack

Product Description

The PARKER MP11044 is a brass compression tube nut designed to secure tubing in compression-style fittings. Threaded at 11/16-20, it mates with standard compression fitting bodies to create a leak-resistant mechanical connection without soldering or brazing. Compatible with 1/2-inch outside diameter tubing, this nut is machined from brass for corrosion resistance and reliable seating under repeated service cycles. Plumbers, HVAC technicians, and refrigeration mechanics install this style of nut when assembling or replacing compression fittings in fluid and gas line applications. It is sold in a pack of 10, making it practical for shop stock or multi-connection jobs.

This compression tube nut is suited for residential and light commercial plumbing, HVAC refrigerant line work, and similar applications where compression-type connections are specified. It is used anywhere a 1/2-inch OD tube must be terminated into a compression fitting body. Typical install scenarios include water supply lines, instrument tubing, and low-pressure fluid transfer systems. The 11/16-20 thread size is a common dimension in the Parker compression fitting line.

Key Features

Compatibility

Designed as a replacement or spare compression tube nut for use with Parker compression fitting bodies accepting 11/16-20 threads and 1/2-inch OD tubing. Confirm thread specification and tube OD match before installation.

Installation Notes

Installation is performed by plumbers or HVAC technicians as part of compression fitting assembly. Before servicing any line, shut off the fluid or gas supply and relieve system pressure. Hand-thread the nut onto the fitting body before applying tool torque to avoid cross-threading. Follow applicable IPC or system manufacturer guidelines for compression joint assembly and leak testing.
