Questions and answers of the customers

Q Is 13MHP-050-075 a valid part? It isn't listed in the sizes and dimensions chart.
A Yes, the correct part number is 13MHP-050-075. We neglected to add this SKU to our sizing and dimensions chart. That information has now been added. Nice catch!
Q What's the difference between this and your single pin clamp?
A Hello and thanks for writing in. The bolted clamp and single pin clamp will achieve the same results in that they will make a secure tri-clamp connection. The difference between the two really comes down to ease of installation. While the bolted clamp requires two hex nuts to be secured the single pin only requires one making it easier to assembly and disassembly. The price of the single pin is less than the bolted. Given this and the ease of use I always recommend use of our single pin clamp.
Q I'm ordering a bunch of these bad boys. Do you offer volume discounts? Thx.
A Hi, thanks for asking. I always appreciate the bargain hunters out there. Sanitary Fittings prides itself on being the low-cost provider of quality stainless steel products online. We will make every attempt to match a competitors price but there are some cases where even we cannot compete. We do not offer standard volume discounts because of our already low pricing. However, if you are looking to place an unusually large order by our definition please run it by us and we'll see what we can do for you. Hope this helps!
