Parker MP11031 Compression Tube Sleeve Brass

Product Description

The PARKER MP11031 is a brass compression tube sleeve designed to create a secure, leak-resistant connection in compression-style tube fittings. The sleeve, also called a ferrule, seats between the fitting body and compression nut to grip and seal the tubing as the nut is tightened. It is a critical component in fluid and gas distribution lines across HVAC, plumbing, and related mechanical systems. Fabricated from brass, the MP11031 offers good corrosion resistance and reliable deformation characteristics necessary for a proper compression bite. Licensed plumbers, HVAC technicians, and pipefitters typically install this sleeve during assembly or repair of compression fittings.

This sleeve is suited for use in residential and light commercial installations where compression-style tube connections are specified. Common applications include copper or compatible tubing runs in refrigeration lines, water supply, and instrumentation piping. It is sold in package quantities of 25, making it practical for stocking on service vehicles or in shop inventory for repeat-use fitting work.

Key Features

• Brass construction provides corrosion resistance and reliable compression deformation
• Compression end connection type for tool-accessible, no-solder tube joining
• Sold in packs of 25 for efficient stocking and service use
• Sleeve design seats firmly between fitting body and compression nut for a leak-resistant seal

Compatibility

Designed as an OEM-style replacement sleeve for use with standard compression tube fittings in HVAC, plumbing, and fluid distribution applications.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off and relieve pressure from the line before disassembling or assembling any compression fitting. Ensure tubing is cut cleanly and deburred before seating the sleeve to prevent improper compression and potential leaks. Do not over-tighten the compression nut, as excess force can distort the sleeve and compromise the seal.
