Brennan Industries” custom designed fittings address unique design problems where standard fittings are not feasible. Designers provide specs of the desired custom fitting, and Brennan provides a drawing, prototype, or production run of the fitting. Brennan can also manufacture one custom fitting if only one is needed. Brennan is capable of quickly turning around all requests, which include different thread combinations for steel, stainless steel, or brass fittings — often within two weeks.
