Burger & Brown Engineering”s Smartflow line of injection molding accessories includes Safe-Lock safety couplers, which mate with standard quick-connect fittings. An internal locking mechanism prevents coupler disconnection when fluid is present inside the line (20 PSI minimum). The non-valved design provides the safety of a valved-coupler without internal flow restriction. Couplers are available with 1/4” or 3/8” flow diameter in straight and 90-degree configurations. Hoses and assemblies are offered along with the Safe-Lock couplers as assemblies or as stand-alone items. All hoses are rated for maximum working pressure of 15 bar (217 PSI). Three hose materials are available. EPDM hose is rated for 140 C (284 F) in red, blue, and black for supply and return-line designation. Silicone 170 C (338 F) and Viton 200 C (392 F) hoses are equipped with stainless steel exterior braid and are well suited for high temperature applications. Hose assemblies may be made to order or assembled on site with a proprietary crimping tool. Safe-Lock couplings and hose assemblies are recommended for injection molding cooling water loops, material furnace cooling, and similar applications where personal safety and shop floor cleanliness are required.
