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

Product Description

The PARKER 61CA-4 is a brass compression tube sleeve designed for use in high-pressure fluid and pneumatic line connections. The sleeve serves as the ferrule component in a compression-style tube fitting assembly, creating a leak-resistant mechanical seal when the fitting nut is tightened onto tubing with a 1/4 inch outside diameter. Rated for working pressures up to 2800 psi and a temperature range of -65 degrees F to 250 degrees F, this sleeve is suited for demanding service environments. Installation is performed by licensed plumbers, HVAC technicians, and industrial piping mechanics working on refrigerant, hydraulic, or instrumentation tubing systems.

This sleeve is used in compression fitting assemblies on 1/4 inch OD tubing in residential, commercial, and industrial applications. Typical install scenarios include instrumentation lines, hydraulic control circuits, refrigerant piping, and compressed air distribution where a reusable, wrench-tight tube connection is required. The brass construction offers corrosion resistance suitable for water, air, and many fluid media. This fitting component conforms to NPTF thread standards and is cataloged under UNSPSC code 27121700 and product service code 4720.

Installation Notes

This sleeve is installed by licensed plumbers, HVAC technicians, or industrial piping mechanics as part of a compression fitting assembly. Shut off and depressurize the line before disassembly or installation. Use appropriate tube cutters to ensure a clean, square tubing end before seating the sleeve. Follow applicable codes including IFGC or IPC as relevant to the system type and jurisdiction.
