This line of universal fittings are manufactured to stricter tolerances than the N30 series imported universal ends, listed on the previous page. The N32D "machined" barbed hose end offers superior retention against coupling blow out (for added safety ends should be coupled with a crimp sleeve). Standard ends are plated malleable iron. Maximum pressure is 150 psi air or water (not for steam service) and safety clips are always required. Universal's are also available in Auto-Locking on request.
