Product Details
O-ring seal from the JSG-9121NS rebuild stack for JET JAT-800A and JAT-821A air hammers. The seal isolates compressed-air paths inside the hammer body so the stroke energy goes to the piston instead of leaking past — replace as part of any rebuild kit operation, never alone if other internals are worn. OEM JET seal.
