Sheaffer Snorkel, Touchdown, & PFM O-Rings
Restoring the filling system on a Sheaffer Snorkel, Touchdown, or PFM is tricky enough, but it can prove useless without the proper parts. The standard off the shelf M1×7 and M1×8 O-rings are the wrong size, and pens repaired with them will not fill reliably. Our O-rings are made to the exact specifications that Sheaffer originally used. Our Viton O-rings are slightly firmer than the Buna-N and are especially formulated for long life in sliding applications like pistons.
Use the small O-rings for the Snorkel and the Touchdown TM (1950-1952)
Use the Large O-rings for the PFM and the 1949 (fat) Touchdown
O-rings are sold in packages of 10.
