Line and End Caps

Smith-Blair brand line and end caps deliver a fast, pressure-rated mechanical closure for plain-end pipe, making them the reliable choice for terminating dead-end mains, isolating abandoned segments, capping blowoffs, and sealing off branch lines ready for future expansion. Easy to install, remove, and reinstall, they give your crew the flexibility to work confidently whether you're conducting a pressure test today or protecting a pipeline until the next phase of your system is ready.
