Manifold System

Build the Manifold System
The manifold creates a hard connection between the reservoirs, gauge, intake, pressure controller and the vacuum source. The parts should be assembled as shown below.

Important: These instructions are for the Mini, Basic, and Plus version of the V2 vacuum press system. If you are building the V2 Premium, be sure to follow the instruction set found here.

Warning: Brass products may contain chemicals known to the state of California to cause cancer or reproductive toxicity.

Parts used in this section:

Brass hex nipple (2)
Brass cross fitting
Brass "street" tee (2)
Vacuum gauge

1/4" Brass barb fitting (elbow)
1/4" Brass barb fitting (straight)
3/8" Brass barb fitting (straight)
1/4" NPT Vacuum valve

  1. Place two passes of thread sealing tape on each of the male threads in the manifold. Make the passes in a clockwise direction following the threads.
  2. Attach the two brass hex nipples to opposite sides of the brass cross fitting.
  3. Attach one brass "street" tee to each of the brass hex nipples. Be sure to use the middle opening on the tee as shown the diagram below. When tight, the fittings should be pointing the direction as shown in the diagram.
  4. Attach the vacuum gauge to one of the street tees.
  5. Attach the brass barb elbow fitting to the brass cross as shown in the diagram below. The fitting should point downward - in the same direction as the male threads on the street tees.
  6. Attach the 1/4" brass barb fitting (straight) to the remaining open side of the brass cross.
  7. If the needle on the gauge is not resting at zero, you may need to release the pressure inside the gauge housing. Carefully lift the brass, plastic, or rubber insert (depending on the model version) at the top of the gauge. Any excess pressure inside will escape and the gauge needle will reset. If you are using a glycerin filled gauge, be sure to keep the gauge in the upright position to minimize loss of the fluid inside. If a few drops of the liquid come out, don't worry about it. Just wipe it off with a paper towel. Be sure to re-install the insert fitting when finished.
  8. Attach the vacuum valve to the other street tee.
  9. Attach the 3/8" straight brass barb fitting to the vacuum valve.
  10. The final assembly should appear as shown in the picture below.
