Direct from Dixon Valve Today:
It has come to our attention that some fittings sold as Surelock Quick Acting Couplings may not meet Dixon Valve pressure rating standards. It has been determined that the 500 psig working pressure rating may not offer an appropriate safety factor.
We are asking all distributors to take note of Dixon’s new maximum working pressure rating of 200 psig. Please remove all Surelock couplings with hose shanks, which are being used at pressures above 200 psig, from service.
Dixon is taking all necessary steps to ensure that all fittings of this type thoroughly meet all Dixon Valve quality standards. Please contact your nearest Dixon branch for a RGA and credit will be issued. We apologize for this quality alert as Dixon Valve is committed to providing the best quality product available.
