DGX Premium DIN Fill Adapter Side View Top View
  • Fits all 200-Bar and 300-Bar DIN valves
  • Rotating head adjusts to conform to the orientation of the fill whip
  • Knurled hand wheel for easy attachment and removal
  • Adapter is suitable for filling ONLY

If you have filled cylinders with 200 and 300 Bar DIN valves then you have probably used the really annoying one-piece DIN-to-Yoke fill blocks. The Premium DIN-to-Yoke Fill Adapter is a much better solution because it uses the same system for connecting to the cylinder valve as scuba regulators. This premium fill adapter has a knurled metal hand wheel for easy attachment and removal, no wrench needed. Even better, because you can orient the yoke fitting a full 360°, the adapter adjusts to accommodate the orientation of the fill whip, not the other way around. That means no more fighting with the whip to attach it to the cylinder.

The adapter accepts standard size o-rings and fits all 200-Bar and 300-Bar DIN valves, but this adapter is suitable for filling only.

  1. 300Bar valves may need lower threads cleaned

    By

    on

    I have 300bar DIN Thermo valves and I had problems with it seating. The DGX support team (Mark/Ian) were great responding and supporting. As it turns out my issue was that the lower threads near the seat of the internal of the valve get rarely used (most regs are 200Bar DIN) and so the lower threads get a little more buildup of junk which adds to the resistance. I was hesitant to tighten more than hand-tight since the valve metal is brass. So if you are using 300Bar DIN valves clean and uses a little force (adjustable pliers) the first go-around. After that it works great with hand-tight torque.

    Good and sturdy, easily makes ready an HP tank to be fillled at a yoke only air fill station. Portable enough to add easily to my dive tool kit.

Damaged 300 bar DIN valve outlets

We occasionally hear from a customer that a new 300 bar DIN fitting on an adapter, gauge, fill whip or even a regulator is not compatible with some or all of the existing 300 bar DIN valves on their cylinders. Unfortunately the problem is more likely to be that the 300 bar DIN valve outlets have received an impact on the edge of the opening and are warped very slightly out of round. This causes a brand new fitting, perfectly within specification, to not be able to screw all the way in to the bottom of the warped outlet on the valve and fail to completely seat the sealing O-ring. However, it is not unusual for an existing regulator fitting or existing shop fill whip fitting to be able to seat because their threads are worn.

You should replace the valve, but sometimes the outlet is only very slightly out of round and might be made usable by a process known as "chasing and cleaning" the threads. You will need something to chase the threads and unless you are a machinist you are not likely to have the proper tools handy. We suggest using a HP DIN Sealing Plug and a wrench, or a Yoke Insert and a hex key, but in a pinch you could use a DIN Fill Adapter block and a pair of larger slip-joint pliers. Use the tools to force the fitting to screw tightly all the way in to the bottom of the 300 bar DIN outlet then back the fitting out completely and blow out the opening; repeat several times until the fitting easily screws in to the valve.

The risk to chasing and cleaning the threads is you damage the makeshift tool instead of correcting the valve outlet. It really only works if the outlet is very slightly out of round, so subtle that the warp is not readily apparent to the naked eye. If the valve has a noticeable ding at the edge such that it is clearly out of round, trying to chase and clean the threads won't work and you will have to replace the valve.

The DIN SCUBA valve outlet is British Standard Pipe Parallel "G" Series (BSPP) 5/8-inch DIA X 14 TPI with 55 degree pitch Whitworth thread form. Very few dive shops have the relatively expensive tapping tool needed to re-thread a DIN outlet; best practice says that valves with damaged threads should replaced because re-threading might remove too much material and weaken the connection.
