Parker 61CA-6 Compression Tube Sleeve Brass 3/8 in

Product Description

The PARKER 61CA-6 is a brass compression tube sleeve designed to create a leak-tight mechanical connection in compression tube fittings. The sleeve seats between the compression nut and fitting body, biting into the tube OD to form a secure, pressure-rated seal without pipe dope or thread sealant. Rated to 2800 psi and a temperature range of -65 to 250 degrees F, the 61CA-6 is built for demanding fluid and gas line applications. It is compatible with 3/8 inch OD tubing and conforms to NPTF thread standards. Licensed plumbers, pipefitters, and HVAC technicians typically install this component in refrigeration, hydraulic, and instrument-grade tubing systems.

The 61CA-6 sleeve is used in residential and commercial applications where a reliable compression-style tube connection is required. Common install scenarios include instrument tubing runs, refrigerant line sets, hydraulic control lines, and compressed air systems. The brass construction suits environments where corrosion resistance and moderate pressure handling are both priorities. This sleeve is sold individually but carries a minimum order quantity of 5 units, making it well suited for service technicians stocking repair kits or contractors building out panel or equipment connections.

Key Features

• Brass construction for corrosion resistance and reliable seating on tube OD
• Rated to 2800 psi maximum working pressure
• Wide temperature range: -65 to 250 degrees F
• Fits 3/8 inch OD tubing for compression-style fittings
• NPTF thread standard for pressure-tight connections
• Compact sleeve design compatible with standard compression nuts and fitting bodies

Compatibility

Designed as an OEM-style replacement or service sleeve for 3/8 inch OD compression tube fitting assemblies. Specific system compatibility was not provided in the product data; verify fitting body and nut dimensions before installation.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians. Always depressurize and isolate the line before disassembling any compression fitting. Seat the sleeve squarely on the tube OD and hand-tighten the compression nut before applying final torque with an appropriate wrench. Inspect the sleeve and tube end for burrs or deformation prior to assembly to ensure a proper seal.
