TimG 62 Posted December 6, 2022 Hey guys Christmas is coming and I thought I might treat my 22-year old ULCS arms to new o-rings.... They deserve it. I know they are 1" o-rings but does anyone know the exact size to use for ordering; and, maybe as important, a good place to order them from? I just took a look on Bluewater's website and a pack of 25 ULCS o-rings were $6.95 (sounds fair enough) but the $10.95 shipping to Miami didn't sound great! A pack of 25 would be perfect.

Jock 14 Posted December 11, 2022 (edited) Here is what ULCS says about their O-Rings (https://ulcs.com/care-and-maintenance/): O-Rings The O-rings in the balls of the adapters will last one to two years if not left out in the hot sun all the time. They will crack, but this will not affect the clamping ability of the clamp. They should be changed when they are cracked, hardened or the arms do not seem to be holding as well as when new. It is easy to forget about the O-rings and recommend replacing them every 2 years. They can be difficult to remove and best if sharp objects are not involved in their removal. The best way is to squeeze with thumb and forefinger, pushing together while at the same time trying to move it to the side. This should give you a small amount of the O-ring to then roll over the ball. To install the O-ring, stretch it over the ball and into the groove. You can purchase new O-rings from Ultralight or maybe from your local hardware store. The ball O-rings are Buna, Size 2-209N70 and the O-rings for the base adapters are Buna, size 2-113N50. We also have a video to show you O-ring removal and maintenance. Tim, every 2 years, not every 22 years! Edited December 11, 2022 by Jock Share this post Link to post Share on other sites
TimG 62 Posted December 11, 2022 Thanks Jock! 2 years, 22 years… it’s in the ball park, right?! I’d seen the ULCS guidance in those first two paras but, curiously, not the part you highlighted in bold which is super helpful. Thanks! The original ones might need explosives to remove them. They are SOLID! Share this post Link to post Share on other sites
