1.Integral stop ring provides piston blow-out protection.
2. Double-acting for positive retraction.
3.Baked enamel outside finish and plated pistons provide superior corrosion resistance.
4.Safety valve in retract side of cylinder helps to prevent damage in case of accidental over-pressurization.
5. Interchangeable, hardened grooved saddles are standard.
6.Plunger wiper reduces contamination, extending cylinder life
