This listing is for:

One (1) basic O-Ring seal kit, for the Crosman
models 150 & 157 CO2 pistols.

Five (5) seals are included in this kit:

One (1) tube cap, URETHANE o-ring seal.
One (1) piercing body, (front) o-ring seal.
One (1) exhaust valve, o-ring seal.
One (1) bolt, o-ring seal.
One (1) extra bolt, o-ring seal.
                                                                                 
Included in this sale is a printed copy of an exploded view
& parts list showing seal locations & part numbers.               
Also included is an additional earlier exploded
view with the E-Z seal ID guide.                                                  
                            
Important Information: Both .177 & .22 bolts (on the guns
listed above) use the same size (Crosman #130-033) o-ring seals,
this is easy enough to verify by looking at the part numbers on
original EVPs, and by comparing the depth and width of the
0-ring grooves on original  bolts. 

Please contact me if you have any questions.

Thank you.
