Installing Seats
Put long stem through first, then stretch seat to get over the small stem. This is easy with larger valves but can be difficult with 1" valve. For 1", put the seat in a vise---squeeze the seat to stretch it.

Orings for Wine Ball Valves
2 orings per valve.
Please note. Do not mix seats between valves---this may cause leaks as the teflon will slowly form itself to its original valve. Teflon "cold-flows". This means it changes shape under pressure. Teflon seat will last virtually forever if it remains with the original valve.
