Prestaflator 3-Way Spin Head Rebuild Kit - 2 Packs – Replacement O-Rings & Presta Valve Washers for Prestaflator Inflation Tools – Durable Buna-Nitrile Rubber Seals for Reliable Tire Valve Connection

Took me a while to figure out what I had bought. Look carefully at the photo to be sure you understand what you’re getting. There’s one large hole piece and six small hole pieces. But one of the six small hole pieces has a thinner rubber diameter (~1.6mm) than the other five (~2.4mm). I needed the small inner ring to replace the one in my Lezyne pump with presta adapter. This requires the thinner 1.6mm small ring, not the 2.4mm. The thicker rings are for what the description says: washers for the presta valve on the wheel. That being said, seems like a high cost for such little pieces of rubber.

This one is my fault, I didn't read the full description.I needed one more of the large rings!
