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.Swivel Joint Clamp w/ Wing Nut Part Numbers & Dimensions
