Making LP Valve Seats for Second Stage

[rsingler]

Try your hole punch on this from McMaster Carr:
Part #86075K24 - 6"x6" sheet of 1/6" thick Viton Duro 75 rubber.
Much smoother under the microscope than inner tube, and firmer.
$17.28 Each

For regs that have thicker seats, you can get 2mm Buna-N nitrile rubber:
Part #86495K34 $18.82
The surface on this isn't quite as smooth as Viton, but still good.

Hey all! Are you all using some adhesive on the lp seat?

Generally not. Most seat holders have a little ridge that holds the seat well, and is course it's trapped under the knife edge except when the valve opens.
