Midwest Fasteners Nylon Plastic Compression Sleeve Ferrule for Compression Fittings

Midwest Fasteners Nylon Plastic Compression Sleeve Ferrule for Compression Fittings

The Midwest Fasteners nylon plastic compression sleeve is a molded ferrule designed to seat against the tubing and fitting body, creating a secure seal inside a compression connection. This family of replacement sleeves is available in sizes ranging from 1/4" through 5/8" (1/4", 5/16", 3/8", 1/2", and 5/8"), with each option sized to match standard compression fitting dimensions for its corresponding tube size. Molded from durable nylon plastic for consistent, repeatable sizing, these sleeves are sold as individual replacement or service parts rather than complete fittings, making them a straightforward pick for rebuilding a compression joint or replacing a worn, deformed, or missing ferrule. Because nylon will not seize, corrode, or bond to the tubing or fitting body the way a metal sleeve can, these sleeves are a practical choice whenever future disassembly or re-service of the connection is expected.
