Seal kit for Benjamin model 310, 312, and 317 air guns contain all required parts needed to reseal this airgun, plus exploded drawing and tube of oil.

Beware of lesser quality seal kits! Our seal kits are guaranteed to work. If you cannot repair your airgun yourself you can send it to our Authorized airgun repair center for repair, and we’ll deduct the cost of the seal kit you purchased from the total on your repair. Proof of purchase is required, so keep your order number handy.

Kit includes all required parts needed to reseal your airgun plus a tube of oil, and exploded drawing.

This is not a cheap “O-Ring” kit. It’s a seal / re-seal kit made with parts closely resembling the originals needed to actually reseal your airgun to restore power. If your airgun leaks CO2, air, or isn’t shooting as hard as it should our reseal kits will get them shooting good again when properly installed.

    I recently received a 317 seal kit, SKU# B-310-5K. It includes both a lead seal and a rubber seal. My 317 had 2 lead seals. Does the rubber seal get installed toward the front or the rear of the valve, if you considered the front to be toward the end of the barrel? Thanks for your help!

    • Donnie R


      The rubber seal goes on the front, meaning toward the muzzle.

    I have a Benjamin Model 317 and it does not hold compression In you add it states the plunger has to be returned to your company before kit is sent Can the plunger be removed without the tool and how is the the plunger sent to your company

    • Donnie R


      That is not the case for the 317. You have to send in the plunger for the 13X series of pistols. Not the 317.


  3. James Sharp

    You mentioned a tool for the rebuild kit but failed to mention the price of that tool.

    • Donnie R


      That would be the optional tool on this very listing.

      The price is listed there.

    Hello would this kit be for the 312, 177cal most I have found are for the 22 cal only

    • Daymon

      The Benjamin 312 is .22 caliber. If you have a .177 it is a Benjamin 317 (assuming it looks like a 312). This kit is for the Benjamin 310, 312, and 317 models.
