Seal off unused PEX or PERT lines quickly with this Flair-It PEXLock 3/8" plug. Made from high-grade malleable polymer with a stainless steel clamp, it resists freezing, cracking, and extreme heat for long-lasting performance in residential and commercial plumbing systems.

• Size: 3/8" PEX compression plug
• Malleable polymer body with stainless steel clamp
• Resists freezing, cracking, and extreme heat
• Works on PEX or PERT pipe
• No special tools required - squeeze clamp ears with pliers until they click or overlap

Tip: Make a square, deburred cut on the PEX before seating the plug; a clean cut helps the clamp seal evenly around the pipe.
