In Topic: Identifying Oring Materials from different Manufacturers

30 April 2013 - 11:55 AM

 

I can not figure out, why you need different lubricants for all your o-rings, when only one can do the job.

 

It is very important to use the proper lubricant for the type of o-ring you have. The wrong lubricant will swell or dry out the elastomer and the o-ring might not seal anymore. Swelling is not that bad usually, though it will weaken the material. Drying out the o-ring will make them brittle like an old rubber band.

I'd throw the Tokina 12-24 into the mix. I've never used it for video, but I use it a lot for stills both u/w and topside and have been very happy with it. http://www.dpreview....ina_12-24_4_n15

A couple days at room temp are no problem at all. You'll need to heat the o-rings to about 200-250F before compression set becomes a concern.

In Topic: Port "throat" sizes Ikelite/Aquatica/Subal etc

It's a no-go for Ikelite as well. The Ike ports are ~85mm ID without the zoom ring and ~80mm with the zoom ring.
