    We do not offer a double-bolt clamp for DIN fittings.  We do however offer the ASME BPE Double-Bolt Clamp.  Sizes and dimensions can be found on the product detail page.
    6. Hello, what is the difference between alfa laval 13mhp and A13mhp
  6. Q Hello, what is the difference between alfa laval 13mhp and A13mhp
    A Hello. We don't offer any products manufactured by Alfa-Laval. That being said, I did visit their website and could discern no notable differences between the 13MHP and A13MHP. I'm sorry that we could not be or more help to your question. We, of course, do offer the 13MHP as a standard product.
    7. What is the operating temperature range of the clamps? How low can they go?
  7. Q What is the operating temperature range of the clamps? How low can they go?
    A The operating temperature of these clamps is dependant upon the material selected for the tri-clamp gasket. Different materials are able to withstand different temperatures. Our lowest-rated temperature gasket material is Teflon which is rated at -250 Degrees Fahrenheit. Read about more gasket information here.
    8. Could you confirm that these clamps are ASME rated?
  8. Q Could you confirm that these clamps are ASME rated?
    A Our High-Pressure Tri-Clamps are not ASME rated.

  12. 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!
    13. What's the difference between this and your single pin clamp?
  13. 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.
    14. I'm ordering a bunch of these bad boys. Do you offer volume discounts? Thx.
  14. 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!
