Cam and groove couplings have been factory-made to the US Military specification MIL-C-27487. This specification covered the sizes and dimensions, machining tolerances, materials, closing rotation, part numbers, pressure ratings, finishing, inspection procedures and packing requirements of the product. Compliance to this specification ensured inter-changeability of parts from different manufacturers.

The individual parts made for the US Military applications generally complied in full with MIL-C-27487, in respect of stamping of part numbers, inspection, packaging and anodizing. Such products were ordered using the specific MS part numbers within MIL-C-27487. Typically, parts supplied for commercial applications only complied with the material, dimensional and pressure parameters of the specification. Please make note that only some of the sizes and materials offered were covered by MIL-C-27487.

Lately, many generic products have been produced which only slightly fulfil the specifications due to other materials used, reduced wall thickness and a smaller amount inspection being provided. Even though this process helps reduce cost, it harmfully affects the life of the product. It can also put the operator in danger and/or expose the environment to danger.

Here at Pacific Fittings, the basic configurations of cam and groove couplers we supply are designed to interchange with products made to DIN 2828, A-A-59326 or MIL-C-27487. For further specification and details please refer to our camlock fittings specifications page.

The general dimensions for our camlock couplings can be found on the camlock fittings specifications page.

Two options exist; whilst shopping or at checkout. Whilst shopping, scroll over the cart icon in the top right hand corner and select 'view cart'. Select 'estimate'. Note both the suburb and postal code fields need to be entered.

A Certificate of Conformity can be provided upon request. Material certificates and/or DIN 2.1.b certificates can also be provided if needed. DIN 3.1.b certificates can also be supplied but will affect the price and delivery. This must be requested at the enquiry phase and confirmed when ordering. Please contact us for any special certifications or product test report requirements you may have..

Pressure ratings as well as many other specifications on our cam and groove couplings can be found on our camlock fittings specifications page.

All steels have the same basic iron and carbon composition, but stainless steel also contains chromium— an alloy that gives stainless steel its corrosion resistance. Stainless steel must contain at least 10.5 percent chromium.

The two most common stainless steel grades are 304 and 316. 304 contains 18% chromium and 8% nickel while 316 contains 16% chromium, 10% nickel and 2% molybdenum. The molybdenum is added to help resist corrosion to chlorides i.e. for use in more saline and chloride-exposed environments like sea water/ coastal areas/ heavily salted roadways. 316 stainless steel contains molybdenum, 304 doesn’t.

304 is an economical and practical choice for most environments. It just doesn’t have the chloride resistance of 316.
