Charging Yokes

3000 PSI charging yokes are made to fit standard scuba tanks. These valves are called K-Valves. Airguns share a common air yoke when they use  Foster 5type fill inlet. The air yoke has a Female Foster Quick Connect on the end of a Braided Stainless line. The yoke has a bleeder and small (1”) output gauge. The output gauge can be upgraded to a 2” Stainless Steel Liquid filled gauge.
4500  PSI Valves can be Din or SCBA. The yokes we sell are SCBA which are a Firefighter, Hazmat and EMT standard. DIN is SCUBA Standard. Both can work well. The High Pressure Yokes are 5K Rated and they can be used to fill the Tank thru the Yoke. You just need to get a Double male to accomplish the connection.

Universal Fittings

We fit male Foster type Quick Connects to your various guns specific adapters so you can fill all your PCP’s with the same air yoke. Gone are the days where you need six complete filling adapters for six PCP’s. Males fitted to various charging probes and the larger Faster Quick Connect can usually be accomplished for a nominal fee per adapter or probe. We have premade fittings that female BSP 1/8” threads with seal and other side is Female 1/8” NPT for the Foster male to screw into so we can switch the British probes, banjos and QC’s over to the Foster Standard using these items. We have fittings with male BSP 1/8” on one end and male NPT 1/8” on the other. Used to put Foster Females on BSP 1/8” Hose ends. This means we can connect British straight pipe to Tapered NPT safety and it will seal. Brit stuff to American & Vice Versa.

To Pump or Not

If you want to pump your gun to its max after topping up the gun with what you have left in your air tank. It is easy if you have the right set-up. Pump hoses nowadays invariably terminate in a Foster Female QC. If they don’t you switch them so they do. It has become the industry wide standard in both the Painball and Airgun industries which share a lot of gear. When you pump you can use a real short line to maximize pump effectiveness or a longer low volume microline which will accomplish the same(less pumps to a given pressure). The gun starts seeing added pressure with far fewer strokes when the line volume between pump and gun is minimized. The hot tip is to have the Female Quick Connects on the hose ends of the pump as well as the yoke so you can change charging adapters and fill different guns without tools. Most Take the Foster Female directly but if they don’t make sure the Probe/Banjo/QC is modified to have a Male Foster on its inlet side.

Double Males

The Double Male Fitting has allowed the transfer of air from one yoke to another or tank to tank. It also facilitates filling your tank through your yoke (providing it is appropriately rated) at places that have only the Foster Female on their Hose end to connect things to.
