Built to the same exacting standards of JCM, 471 Carbon Steel sleeve is furnished with a plain outlet with options including beveled for welding, square/butt cut and custom outlet/neck lengths.
JCM 471 Carbon Steel Fabricated Tapping Sleeves
Built-in benefits make these heavy fabricated steel sleeves increasingly popular for making larger taps on all types of pipe. 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.
Built in range – accommodates pipe industry tolerances and non-standard pipe diameters.
Ease of assembly – eliminates extra equipment, time and specially trained personnel.
Ready availability – taps can be made without long delays – even taps on special sizes of pipe – or services requiring high pressure flanges.
Direct reinforcement of the pipe – eliminates flexing or deflection of pipe opposite the tap. Large gasket cross section set in retaining cavity – provides a positive initial seal which increases with increases in line pressure.
Heavy steel sleeve – eliminates deflection possibility. Most important, JCM Fabricated Tapping Sleeves assure a safe dependable tap.
