Product DescriptionThis LOT of 6 Assorted 2½”-4½” Sanitary Style Clamps w/Extra o-rings appears to be in good/fair cosmetic condition showing some signs of previous use. (Please see the pictures above for more detail.) One of the clamps is missing the Lug Nut as shown. There will be 16 o-rings included in this listing. I do not have the proper equipment needed to formally test this LOT; therefore it is being sold as is. http://local.alfalaval.com/en-us/key-industries/dairy/pumps/Documents/Fittings_Brochure.pdf |
