Sioux Chief 649Y Series PEX SDR9 Mechanical Cinch Clamp, USA-Made

Sioux Chief 649Y Series PEX SDR9 Mechanical Cinch Clamp, USA-Made

The Sioux Chief 649Y Series Mechanical Cinch Clamp is engineered to secure PEX SDR9 tubing onto fittings, creating a tight, leak-resistant joint on PEX SDR9 piping systems. The series is available in 1/2", 3/4", and 1" sizes across the 649Y2, 649Y3, and 649Y4PK1 configurations, letting plumbing contractors and stocking distributors match clamp size and pack quantity to the tubing size a given job requires. Every clamp in the 649Y Series is manufactured in the United States and is engineered strictly for PEX SDR9 piping; it is not designed for use with polybutylene (PB) tube. The cinch-style clamping action compresses evenly around the tubing and fitting barb for a consistent, dependable seal at every connection.
