I've just bought a DIN converter to replace the A clamp on my apeks 1st stage but I want to fit it myself rather than get the LDS to do it.
The nut on the A clamp I need to remove is 19mm diameter but the yoke won't allow an open-ended spanner in, a regular socket fits but I can't get at the square hole with any of the ratchet fittings, so it can't be turned
Does anyone know if a regular 19mm ring spanner will fit or does it require a special Apeks tool?

Steve - I`ve just worked it out & done it. Tools needed are adjustable monkey wrench (not the spanner but the one that has 2 prongs so when adjusted the `square` gets bigger/smaller) and a workmate (not necessarily the black & Decker type that I use !!)

If you look at the yoke, it is the same diameter as the nut so line up the sides of the yoke with the nut, apply the wrench around the lot, adjust until tight. Then jam wrench handle in workmate and twist the first stage in rhe right direction. BINGO. Leave the black plastic thing in place, make sure the o-ring comes out with the nut and fit the adapter, tightening with the appropriate allen key.

Silly question but why did you not just send the reg to Apeks who will fit it for free?

Cheers for the info Kirky, I'm still not quite sure about the type of 'two pronged' monkey wrench you're referring too but I'm sure my local hardware shop will sort that out.

Re your question Drifty, speaking for myself only, I always prefer to do mechanical/electrical/etc things myself wherever possible, especially as I may have to refit the a-clamp to dive abroad.

Steve, getting my apeks converted tomorrow. Have to admit im getting the shop to do it but your right. Much better to be self suficient at repairs.

You don't need to replace the A clamp abroad, even if they don't have DIN fittings just use an adaptor (about £20) Or you can even borrow mine

Cheers Andy, That's very kind of you to offer, though apparently DIN fitting tanks are more widely available than I had believed.

Cheers Kirky, I sorted it using a variation of your method, (a-clamp in a vice, no need for wrench) but kudos to you as I hadn't thought of that myself.

The simplest.......and most cost effective is as follows.
Buy 300 mm ish. of 3/8" or 9/16" (lp & hp ports) threaded bar. This is your field vice/handle.
Remove all hoses and place yoke nut in vice jaws, use field vice as handle and simply undo nut by turning 1st stage with handle !!!!!
The delux version has electric tape round the thread to protect your soft northern hands.
Beware when tightening din shaft (6mm allen key)that brass is soft as well !!!!
~Nice web site~not too mutch bollocks
safe diving
