Which piston seal works best in HW50 .177. Looking at the Vortex or the Air Rifle Headquarters seals. Thanks, Don
Yogi was referring to Custom Air Seals in Australia. They make 26mm seals for HW50s, among many other seals. Theres two different options, a green one and a red one. You can find their site by google, or via ebay. If thats your preferred seal choice.
You will still need to size the vortek (or any seal) depending on the fit.. In my opinion, the idea that a vortek seal does not require sizing is a misinterpretation. A seal should fit the receiver's diameter and provide a certain amount of resistance. Too little or too much and you will not have the full efficiency of your power plant.CAS gives the diameter of their seals, I think they're around 26.5 mm IRC. ARH has like 3 seals for the HW50 of varying sizes specifically due to what they say are varying tolerances to receiver tubes. I don't know the diameter of a vortek HW50 seal, never measured one, but more important would be to know the ID of your receiver tube to make sure you're not buying an undersized seal, and can size it appropriately.
