Description

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.
