Built-in benefits make these heavy fabricated steel sleeves increasingly popular for making larger taps on all types of pipes. By placing the design emphasis on eliminating problems inherent with older pipe and field installations, JCM Fabricated Tapping Sleeves have taken the complexity out of tapping or branching pipe.
