Parker 61P-4 Compression Tube Sleeve 1/4 Inch Brass

Product Description

The PARKER 61P-4 is a brass compression tube sleeve designed for use in compression-style tube fittings across plumbing, HVAC, and fluid-handling applications. The sleeve seats between the compression nut and fitting body, creating a leak-resistant mechanical seal when the nut is tightened. Rated for a maximum working pressure of 150 psi and a temperature range of 0 to 150 degrees F, it handles standard low-pressure service conditions without requiring solder or thread sealant. The overall length of 0.38 inches fits the 1/4 inch outside diameter tube size. Licensed plumbers and HVAC technicians are the primary installers of this fitting component.

This sleeve is suited for residential and light commercial installations where 1/4 inch OD tubing is joined using compression-style fittings. Common applications include refrigerant line accessories, instrument tubing, water supply lines, and pneumatic control lines operating within the rated pressure and temperature limits. It is sold individually but requires a minimum order quantity of 5 units.

Key Features

• Brass construction provides corrosion resistance and durability in fluid and gas service

Compatibility

Designed as an OEM-style replacement sleeve for compression tube fittings accepting 1/4 inch OD tubing. Compatible with standard Parker compression fitting bodies and nuts of the corresponding tube size.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians familiar with compression fitting assembly. Shut off and depressurize the line before disassembling any existing fitting. Ensure the tubing end is cut square and deburred before seating the sleeve to achieve a proper seal. Do not overtighten the compression nut, as excessive force can deform the sleeve and compromise the connection.
