The Hose Barb Adapter M12x1 is a stainless steel hose barb adapter with an M12×1 threaded connection, used to connect flexible silicone or thermoplastic hose to threaded ports on UIC or VTA distillation and cooling equipment. The barbed end grips the inner diameter of the hose securely, preventing pull-off under pressure or vacuum. Compatible with M12×1 threaded ports on UIC KDL5 and related equipment.
