Seal kit cal.177 for Smith&Wesson 79G | in stock  Seal kit cal.22 for Smith&Wesson 78G | in stock USD 16.00 in stock Shipping (up to 4 kits) USD 4.00 Put an end to the leaking of those otherwise good pistols. Will also fit Daisy 780/790. The kit includes high performace oil-resistant o-rings including a transfer port seal which helps to stop the blow-off and waste of CO2 bypassing the transfer port, resulting in higher velocity! (The original design does not have any seal.) Installation is easy, pin punch required. Comes with instructions, but give it to a gunsmith if you feel uncomfortable. Note: some of our our o-ring dimensions are different from the originals to compensate for the poorly engineered groove dimensions. Guns fitted with our seals hold pressure for several months. Please make sure you order for the correct caliber as seal dimensions differ. •Check Out  Piston seal for RWS/Dianawerk Get maximum velocity using our red high performance parachute design piston seal!

Nowadays, much better products, like synthetic oils, are readily available. Simply install this new design with 2 oil-resistant o-rings. Guns fitted with this piston usually shoot 350fps. 2 replacement seals and installing instructions are provided. Installation is not too difficult.
