DMT brand new water valve top seal & stem seal repair kit. This is a brand new, high quality part. Correct material. Soft, pliable, stainless wire crimp ring. The seals sold by the big box auto parts stores / chains are THICK and hard.
The larger seal is 1.000" in diameter. This fits almost every make and model Ranco valve including part number on your water valve matches the part numbers in the list below. The smaller stem seal is for water valves with a 3/4" OD "leg" directly below the larger seal. Ideally it would be best to disassemble your water valve to verify that the stem seal LOOKS like the one in the picture and to check that the OD is .625"
Note: I have other listings of the Ranco repair kit with a smaller .500" diameter stem seal for tube/leg OD of .625" (5/8")
Material(s) Firm, black Nitrile rubber just like OEM
