Piston Seals

 

For FWB Sporter piston seals see the FWB Sporter category.

 

Use our moly paste for lubricating all of our seals only.

For HW -Beeman Custom Seals.

When installing on the piston, turn the seal several times to set it on the piston before putting in the gun. Why? Seals are made to fit the piston tightly. Most owners create scratches and gouges on the piston securement dovetail-button. This creates the piston to now be bigger and the seal fits tighter or bows out. Turning the seal to make it fit flush is easier than removing it. Next time is the time to file or deburr the piston dovetail.

Also, HW piston variances are extreme. Some seals spin on pistons, others are hard pressed to even fit. So, more slop will be designed in at a future date to help with this situation. Sometimes the rear seal band bows out on the over-sized pistons. Sizing info in this catalog solves that. If you have a lathe and a lathe file, just chuck up the piston and touch the seal for 2 seconds with the file and measure. I can take 5 thousands off in a second. Less is better.

Making the seal bigger in the ID is a quick fix. Just like the factory. However, complaints come in with a loose or shifting seal. In some guns that was actually done to correct an off-center piston. In that case material removal maybe a good option if done ever so slightly to get the seal re-centered on the off-center piston.

Used seals are non- returnable- no exceptions. Unused seals are subject to a 15% restocking fee and limited to 3 days after delivery.

 

 Seal colors change often from run to run. This is normal.

 If you do not see it listed, it is not available or out of stock.

All seals are sold as 1 unit unless noted like TX breech seals and Recoilless RWS seal sets.
