Parker L61CA-6 Compression Tube Sleeve 3/8 in Brass

Product Description

The PARKER L61CA-6 is a brass compression tube sleeve designed to create secure, leak-resistant connections in compression-style tube fittings. The sleeve seats between the compression nut and fitting body, deforming around the tubing as the nut is tightened to form a reliable metal-to-metal seal. Sized for 3/8 inch tube OD, this sleeve is suited for use in potable water systems and other plumbing or fluid-handling applications where a durable brass ferrule is required. Plumbers and pipefitters use this component as a replacement or spare part when servicing or assembling compression fitting assemblies.

This sleeve is intended for potable water applications, making it appropriate for residential and light commercial plumbing lines, supply connections, and similar water distribution service. It is compatible with standard compression fittings that accept a 3/8 inch tube OD sleeve. The brass construction resists corrosion in typical water service environments and meets the durability demands of professional plumbing installations.

Compatibility

Designed as an OEM-style replacement or service sleeve for standard compression tube fittings accepting a 3/8 inch tube OD ferrule in potable water plumbing applications.

Installation Notes

Installation is typically performed by a licensed plumber. Shut off water supply and relieve line pressure before disassembling any compression fitting. Slide the sleeve onto the tubing before inserting into the fitting body, then thread and tighten the compression nut by hand before applying tool torque. Avoid overtightening, which can distort the sleeve and compromise the seal.
