Review: These check valve replacements duckbills work great and fit perfectly into standard 1/4 ABS check valve housings. I have been pumping full 12% chlorine directly through them for about 4 months now and they still look brand new. They are defiantly chemically resistant. Cheap ones degrade fast with chlorine exposure. It is odd that the listing focuses so much on the fact that they are off white because plastic can be dyed any color. So them being off white in no way means they are actually Santoprene. That said they do appear to be what they claim and hold up well against chlorine. Review: These duck bill check valves are a great replacement for chemical feed pumps. I had one that was leaking back when changing tube on Stenner pump. These are easy to replace and durable material. 10 pack should last for quite some time. Great value for the money. ## Features - Rocksteel Replacement for Part MCCVDB0 - Compatible with Stenner Pumps check valve, 1/4" intake for use with peristaltic pumps, chlorine pumps, chlorinators, and more. - Made of Santoprene - Just like the OEM material, these duckbill check valves are made from Santoprene.
