This tool is required for gas charging Penske and other racing dampers after service. The pressure gauge reads to 300 psi (20 bar) for accurate filling. The special coupler is designed to separate hookup from valve actuation so your charge isn't lost when you install and remove the tool from the shock.
To use, screw the coupler onto your damper Schrader valve using the hex near the base of the coupler. Then turn the T-handle to open the Schrader valve. Pressure will now register on the gauge, and you can use the Schrader valve at the end of the tool to pressurize the damper from your nitrogen bottle.
Fits Penske and other brands of racing shocks using a standard Schrader valve. Sold individually.
