5 hood (shell) O-rings for Parker 51 Aerometric

Description

Five New Replacement O-Rings for
Parker 51 Aerometric Fountain Pens
Most Aero-metric (squeeze-filling) Parker 51s use an O-ring that fits into a recess in the hood (also known as the shell) and seals against the clutch ring. The assembly is shown above, with the shell partially unscrewed.
The O-ring is also shown with a shell presented to make the recess clearly visible. If your pen has a shell without a recess, it is not intended to use an O-ring, and attempting to install one may damage your pen. These rings fit standard-sized 51s. Demi 51s use smaller rings, which we also sell.
NOTE: This listing is for five (5) brand-new seals. They are not original Parker manufacture -- Parker has not supplied such parts for many years -- but they are newly made to exact original specifications. The other parts shown in the pictures above are for illustration only, and are not included in this listing.
Payment
We are glad to combine shipping charges on multiple purchases, but it is vital that the proper checkout method be used. When buying more than one item, use the Add to Cart button -- NOT the Buy It Now button. View your cart when you are ready to complete the purchase, and if the total shipping charge is incorrect, do NOT pay. Instead, click the Request Total link at the top right and we will send you a corrected invoice.
Terms of Sale
We strongly believe in full and explicit description of any condition problems or flaws, and in very conservative grading. We stand behind our descriptions -- buy with confidence.
