Securely connect tri-clamp ends with heavy duty, stainless steel single pin clamp (13MHHM)

The single 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.  Sizes on this product range from 1/2 inch all the way up to 12 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 product.

This product should not come in contact with processing media and thus is not offered in 316L alloy option. Clamp connections create a non-permanent join for easy access to clean and inspect line processes.

Questions and answers of the customers

  1. A Hello, this is an interesting question that I have never been asked before. The groove of the single pin heavy duty clamp is going to fit the flange of the tri-clamp connection snugly when properly secured. If I understand your question correctly, you are looking for the height of this groove which should also be equal to the height of the flange. Using a 2" clamp as an example, you can see from the sizing guide chart that the outside diameter is 2.516" and the inside diameter is 1.870". Subtracting these numbers gives us 0.646", however, this accounts for both the height of both flanges combined. Dividing by 2 the height of the flange, and the groove of the single pin clamp, should both be 0.323" or somewhere really close to this. Applying this formula to the 4" version you'll see that the height/groove size increases along with the flange size. I hope this helps, please call with any additional questions.
  2. A The 3" diameter refers the sanitary fitting size and neither the flange, not the tube size. In this particular case the flange will be slightly bigger than 3". The best way to imagine this is to stand your fitting, flange side down on a piece of paper and tracing it. The outside diameter of a 3" sanitary fitting is 3.717". For more information on specific flange, ID/OD, sanitary fitting dimensions please refer to our Clamp Fittings and Gasket Sizing Guide which can be found on most product pages. Thanks for asking!
