These DSX original fittings are made from a solid block of 6061 aluminum and then anodized black and laser engraved. These are very hard to machine due to the unique 45° angle! They make connecting two male GM push connect ends a snap. Unlike other fittings out there that use difficult to deal with backing nuts, this uses stainless steel snap clips inside as well as a double fluorosilicone o-ring seal on each end to provide the easiest installation coupled with leak free operation on even the worst of fluids.
DSX manufactured components are covered against defects in materials and workmanship for the life of the product.
