Tuning Help needed TX200 SR Webley Venom Piston Seal

Looking for a replacement piston seal for a 25mm Webley LazaGlide.

A factory 25mm seal does not fit as the center diameter is too large. 

Any ideas who would have them?

Lewis you'll need a 25mm HW piston seal. The HW piston seal conversion was a common Venom and later V-Mach mod for custom TX200's/PS's. 

My first choice would be a V-Mach 25mm HW parachute grooved seal to keep the internals as true to form (Venom DNA). Hard to find, but they are out there. 

Second would be an Aussie 25mm seal, the red moly impregnated ones.
