Description: Use these square O-rings to repair your HP-41C, HP-41CV, HP-41CX, HP-65, HP-67, and HP-97 calculator card reader. These work better than the round O-rings as they better match to the original HP drive wheel design. These O-rings are used to replace the deteriorated, gummy, card reader drive wheel on HP calculator card readers. You will receive four square O-rings. Enough to perform 2 card reader repairs. O-rings can be slipped in place with or without adhesive. If it is preferred to glue the O-rings, use a small amount of cyanoacrylate (Super Glue). I have repaired the HP-41 series card readers using these O-rings for over 10 years and had very good results. Keep in mind there could be other reasons why your card reader has failed. The drive wheel is the most common failure. Note: You are receiving square O-rings and not the actual HP calculator or HP card reader. Items will be shipped via USPS standard envelope letter. I ship Monday thru Friday until 5:00 PM Central time. I do not ship on Saturday or Sunday. I ship within 2 business days after the transaction is complete.
