This is a nice enough filling station, the price is not shaby on this either.
On this product, you'll have the hose fixed onto your filling station, although, if you have the fittings, you could probably just add the fittings if you have some laying around and make the hose a quick-couple fitting for ease of storage and portability.
The bleeder function is integrated to the main pressure block, although compared to the other, slightly pricier midel, this block is smaller.
This filling station will thread onto the DIN fitting on a scuba tank, w/ a red polymer tap to torque it up proper and create an airtight seal. This tap has debossed lumps on oblong shapes along the tap circumference that helps to torque this fitting up proper onto the scuba tank. a Word of advise though - be sure that, when you do torque this tap up fully, that the male Q/C fitting will point in a direction that will make the attached hose manageable.
The bleeder screw is stainless, which is nicer than the brass ones commonly seen on these Chinese high pressure products. The thread runs smooth enough, whilst the knurling is not entirely the best / isn't perfectly cut, but works nevertheless, just doesn't have a refined touch to it. It also has a filled at the bottom to make it slightly more aesthetically pleasing.
The male quick coupler here is your standard 8mm fitting and looks to be affixed in place w/ thread locker of some such.
The hose itself comes w/ a single female Q/C factory fitted, affixed to an 800mm unusually long hose The coupler here has a plastic male plug to prevent ingress during export/storage, though we don't recommend storing this filling station this way w/ liquid in the gauge, as we've had cases where pressure builds up over a period of time and then the rubber plug on the gauge will lie on the floor one morning when you wake up w/ half the glycerine out on the floor.
The long hose has its set of benefits and if you tend to shoot with a scuba tank affixed to your rifle, then you could put your bottle inside your bag down the side of your shooting table, running your hose all the way up and not need to worry about bumping your bag/tank from the table. The hose furthermore is steel-coil shielded, which will prevent sharp angles from catching your hose, as the steel wire is polished. It should also protect against weighted impact / squashing too.
The gauge itself indicated w/ green only up until 200 BAR and up to 300 BAR in yellow. So it is safely rated for 200 BAR, though you could use this for 300 BAR applications. We've never really had any of these critically fail after a prolonged service life, but as per usual, the risk at your own discretion.
