Vario PVDF hose coupling, 4,0 mm bore

BOLA Vario hose couplings Two-part coupling made of PVDF for connecting flexible hoses (e.g.: Viton®, Tygon®, silicone) to rigid-walled lines made of PTFE, glass, metal or other plastics. The operating principle is simple yet ingenious: The flexible hose is pushed onto a cone and fixed to the coupling with a union nut. On the opposite side, rigid-walled hoses and lines with an outside diameter of up to max. 10 mm can be connected via a GL thread and the matching laboratory fitting. Limited chemical resistance, working temperature up to max. +150°C. Dimensions: suitable for hose inside Ø mm 4,0 + 4,8 suitable for hose wall thickness mm 1,6 bore mm 4,0 connection thread GL 14
