Blind Flange Manufacturer


Our recently acquired New England Tool Co division was established to provide local companies with a source for custom blind flanges for use in welded pressure vessel tanks. Blackhawk Machine is a proven leader as a blind flange manufacturer in the US.

Our blind flanges are produced to your specifications and are delivered directly to you on our truck in most cases. Flame cut flanges are machined and can be marked with part number, material type, material heat number, and supplier ID as requested.

New England Tool Co. has been providing this type of custom blind flange work for over twenty years to some of the largest users in the Northeast.

Flanges are routinely made from pressure vessel steel and stainless steel from 4” diameter up to 20” diameter in volumes from 1 piece to hundreds. Thickness ranges from 3/8” to 2.5”.
