Build the Manifold
The manifold creates a hard connection between the reservoirs, gauge, intake, pressure controller and the vacuum source. It's much easier than it looks, so let's get going!

Parts used in this section: Time: Tools:

Barb fitting - 1/4 NPT-male to 1/4" barb (1)
Brass branch tee - 1/4 NPT (2)
Brass pipe 1.5" - 1/4 NPT (2)
Brass cross - 1/4 NPT (1)
Vacuum valve (1)
Vacuum gauge (1)
Brass fitting - 1/4 NPT-male to 3/8" barb (1)
Brass elbow fitting - 1/4 NPT-male to 3/8" barb (1)

25 minutes

Wrenches or pliers
Thread-sealing tape


  1. Place two passes of thread-sealing tape on each of the male threads from the parts list shown above. Wrap the tape clockwise around the fitting.
  2. Attach the two brass pipes (1.5" long) to opposite sides of the brass cross fitting.
  3. Attach a brass branch tee to each of the brass pipe union fittings. Note the direction of these fittings in relation to the brass cross as shown in the picture below. This is critical.
  4. Attach the vacuum valve to the brass cross as shown below. Again, note the orientation of the handle on the valve. It must be aligned correctly with the rest of the manifold.
  5. Attach the brass barb fitting (3/8" barb to 1/4 NPT-male) to the vacuum valve.
  6. Attach the brass barb fitting (1/4" barb to 1/4 NPT-male) to the open end of the branch tee as shown in the picture below.
  7. Attach the vacuum gauge to the manifold. Note that the face of the gauge points toward the brass barb fitting in step 6. The bubble in the gauge is normal.
  8. If the needle on the gauge is not resting at zero, you will need to release the pressure inside the gauge housing. With the gauge in the upright position, use a small flat-tip screwdriver to gently lift the edge of the rubber insert on the top of the gauge. Release when the needle drops back to the zero position. Do not cut off the rubber top of the fitting. Note that the air bubble in the gauge is normal. This bubble keeps the gauge accurate regardless of altitude.
  9. Attach the brass elbow fitting (3/8" barb to 1/4 NPT-male) to the remaining open side on the branch tee.

The final assembly should appear as shown in the picture below.
