Fixed pipe clamp/eyelet: ZPF pipe clamps offer a secure, strong fitting with exactly the same diversity as the rest of our ZP range. They are ideal in processes where heavy duty activities might knock the clamps and also where higher liquid pressure is used. The clamp is closed by means of a screw. Spigot sizes come in 14mm, 17mm and 20mm for both 11/4″ and 11.2″ OD pipes. Max working temperature 80° C. Max working pressure 5 bar. Materials: Body (polypropylene), Pin and screw (316 Stainless steel) O-ring (Synthetic rubber NBR), seal (Soft polypropylene).
