Parker 61HD-8 Compression Tube Sleeve Brass

Product Description

The PARKER 61HD-8 is a brass compression tube sleeve designed to form a leak-tight seal in compression-style tube fittings. The sleeve, also called a ferrule, is compressed between the fitting body and nut to grip the tubing and create a pressure-rated mechanical seal without soldering or threading. Constructed from brass, it offers good corrosion resistance and is well suited for use in fluid and gas distribution systems. Plumbers, HVAC technicians, and pipefitters install this type of component during assembly or repair of compression-fitting connections.

This sleeve is used in residential and light commercial plumbing, refrigeration, and instrumentation tubing applications where compression fittings are specified. It is a direct-replacement ferrule for systems that use Parker compression-style hardware. Typical installation scenarios include water supply lines, pneumatic control tubing, and refrigerant or hydraulic instrument lines where a re-usable or replacement sleeve is required.

Key Features

• Brass construction provides corrosion resistance and durability in wet and gas service environments
• Compression end connection — no soldering, threading, or special tooling required for assembly
• Single-piece sleeve design seats consistently against mating fitting body and nut
• Sold individually, allowing single-unit replacement without purchasing a full fitting assembly

Compatibility

Designed as an OEM-style replacement sleeve for Parker compression-style tube fittings requiring a brass ferrule insert.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC and instrumentation technicians. Shut off and depressurize the system before disassembling any compression fitting. Seat the sleeve squarely on the tubing before threading and tightening the compression nut — cross-threading or over-tightening can deform the sleeve and cause leaks. Follow applicable IPC or IFGC code requirements for the system type being serviced.
