Gas Inlet Cross 3" Closed Loop - 1/4" Nitrogen Assist Port

This gas inlet end cap valve is made from 304 stainless steel and comes complete with shower head which enables the solvent to be introduced evenly into the material column reducing dry spots.

The attached pressure gauge works to 100PSI with an option of 300PSI.

This product comes as standard with NPT but it's available in JIC, BSP or socket coupler or variants of.

This piece is made to work in conjunction with a gas recovery tank as the 1/4" male NPT thread on the top is used to attach a hose which usually runs back to the reclamation tank.

It is possible to attach a 1/4" female NPT hex nut fitting which will enable the user to inject solvent straight from the can into the material column.

This product comes as standard with 1/4" male NPT thread which allows the user to hardwire their braided hose back to either their vacuum pump or their nitrogen bottle. The upgraded version of this will come with a stainless steel socket coupler. This will allow for quick connection/disconnection of the loop making the whole process more streamlined.

The benefits of upgrading to this gas inlet cross connection are as follows:

• The ability to use nitrogen.
• The ability to vac your system out from the material column.

The benefits of using nitrogen

When running a closed loop system the use of nitrogen can be very helpful as it allows you to move solvent around the system at subzero temperatures without the need for heating the reclamation tank. This lack of heat aids the dewaxing process and results in a clearer end product.

Nitrogen will build up in the system, increasing pressure at subzero temperatures, so bleeding the system will be necessary. This can be done from the reclamation tank or the base.

Vaccing system from the material column

Being able to vac the system out from here is really important if you are wanting to do multiple runs - it enables you to work much more efficiently as you can disconnect your material column and reload while you are still recovering solvent from your base.

There is no need to disassemble the whole rig. BHO's systems are superior in this aspect and save you time.

When you add the column back into the system you will need to vac the system out which cannot be done from the base, as this will be full of oil and solvent. Once the material column is back in situ you will need to vac the hose running back to the reclamation tank and the material column itself, down to the ball valve which connects to the base. This is crucial for two reasons: you don't want a build up of air in the loop, as this can be dangerous when mixed with solvent. Also, if you don't vacuum air from the system, once you add dry ice to the jacket moisture will build up inside the material column, causing problems with filtration and oil purity.
