Vintage Double Hose • View topic - Removing/installing C clips
Personally I would get rid of the clips and get a band clam. I have been rebuilding regulators (including double hose) since the early 70s and I always hated those clips.
I have been using a band clamp on my RAM since 1971 and never had any issues with any of the original clamps or any of the reproduction ones.
In the past, I have had to adjust some of the reproduction band clamps to work with some of the diaphragms, but all the new silicone diaphragms work great with the new band clamps.
With a properly installed band clamp I have never had the cans slip.
I dive most every weekend in salt water and I like to be able to open the cans easily and inspect and clean the dry chamber if needed. I dont open it every weekend, but it is easy to do with the clamp. I prefer to inspect the regulator on a regular basis and extend the interval between rebuild. Normally I only have to rebuild every 5 to 10 years.
I realize that the clips came with most US Divers regulators, but the band clamps were an available upgrade from US Divers since the late 50s.
From an engineering stand point I personally always thought the clips were kind of a kludge. This is just my own personal opinion, but I never liked the concept of deforming metal every time you want to clamp a case close (or to open it). It just doesnt seem right.
This is just my personal opinion and I am aware that many collectors and a few divers do use the clips, but my observation is that the large majority of divers that use double hose on a regular basis prefer the band clamp.
