Flange Boss Flange Spreader

Safe and easy to use, the FlangeBoss spreads flanges evenly and safely during gasket changes and pancake blind installations.
Flange Boss flange spreaders actuate mechanically, pneumatically or hydraulically. The rotating Cam-Wedge design with versatile hex drive attaches to the flanges through the bolt holes, securing flange spreaders to piping so it cannot slip out.
Flange Boss spreaders are available with 25,000 lbs. of spreading force, and fit 1/2″ to 24″ flanges from ANSI 150 lb. to 2500 lb., or DN 15 – 600 (refer to DIN EN ISO 9002 and 6708).

Simply put, the FlangeBoss is one of the world’s safest and toughest flange spreaders. Made in the USA.
FlangeBoss is your safest choice in a pipe flange spreader.
