Securely connect tri-clamp ends with heavy duty, stainless steel double pin clamp (13MHHM-DP)
The double pin heavy duty clamp with a wingnut is made from 304 stainless steel alloy. It is used to join two separate tri-clamp ends to one another and allows for more flexibility than the single-pin heavy duty clamp. A tri-clamp rubber gasket should be placed between the two flange ends to ensure proper fit and secure connection. Do not over tighten wing-nut as this may damage product.
