Folks if you rinse the brass in fresh water you wont need anything. if they stick its only due to salt build up. whatever clips you buy be sure that the springs are either Brass or SS. otherwise they will turn to dust at the "wrong" time. dive on & on hank In a message dated 97-01-25 09:38:32 EST, you write: << Subj: Brass vs. SS piston clips / bolt snaps Date: 97-01-25 09:38:32 EST From: DiveBase@ms*.co* (Lawrence Orchard) To: Kent.Lind@no*.go* (Lind, Kent) CC: wreckdiver@wreckdiver.com (Wreckdiver List) My experience is that the brass snaps are prone to "sticking" unless you keep the piston greased with silicone. I think as the brass becomes tarnished due to oxidisation, its this thin layer that sticks (I'm no metallurgist though). After a while they need greasing again and therefore this adds to the maintenance/preperations prior to a dive. The Stainless Steel ones dont seem to have this problem. The ones I use are not actually SS, but have some sort of chrome plating, however they dont rust or stick. Got them from a hardware store, nothing special about them. Oh except they're cheaper pro rata because they're not sold as diving equipment. :) Regards Lawrence(UK). ---------- From: Lind, Kent Sent: 24 January 1997 19:19 To: wreckdiver@wreckdiver.com Subject: re: Re: Wreck gear rigging We call them bolt snaps up here in Alaska, not to be confused with *boat* clips which are what you call "widow-makers". I've got them on all my gear but they can be a real pain in winter. If the air temperature is sufficiently cold, they will freeze solid on you the instant you exit the water and you won't get them open again until you get your rig home and run it under hot water. Kind of a bother on shore dives when you have a hike. Also, I've heard various times on the lists that stainless bolt snaps are preferred to brass. I have both and I can't detect any real difference. Looks like they use the identical spring inside. Anyone know why the stainless are supposed to be better?
