OLAB fast lock connectors from the 39000 series allow a safe connection for thin gauge hoses/pipes while guaranteeing the pressure seal. The system also removes the need for welding making it ideal for refits or replacements.
A stainless steel reinforcing bush, with an AST patent on the external surface, is inserted in the hose/pipe and along with the olive and o-ring allow the nut, when tightened, to produce a high pressure seal
