Description

Securely connect tri-clamp ends with heavy-duty, stainless steel swivel clamp (A12MPS)

The double-pin heavy-duty clamp with a wingnut is made from 304 stainless steel alloy (Also available in 316).  It is used to join two separate tri-clamp ends to one another.  Sizes on this product range from 1 inch all the way up to 4 inches in diameter.  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 the product.  The recommended amount of tension is to tighten the wing-nut until it becomes snug, then perform one more half twist for the proper amount.
