Q: What size plumbing fittings is this check valve core compatible with?

A: This valve core is designed as an aerator-type, straight-through check valve for standard water supply and drainage fittings. Please measure your existing valve housing or fitting diameter before purchasing to confirm compatibility, as exact sizing can vary by installation.
