Cat 3k133 check valve (high/low pH on Water Wizard 2)

[Rainway]

Anyone know a replacement part number the check valve coming out of CAT 3k133 pH pump - to keep the pump from kicking product back into the pump stand?



Thank you.

Coleman uses the SMC plastic one, but they crack at the threads over time:

I linked the Viton seal one, but the Teflon seal one you linked would be better.
