Air Supply Connections for Blasters

Customers occasionally inquire about the best way to connect their new Vaniman sandblaster to their air supply. The type of tubing and hardware that is being used dictates the best method of connecting the sandblaster. All Vaniman sandblasters include three fittings: a 1/4″ outer diameter quick disconnect, a 1/4″ inner diameter barb fitting, and a 1/4″ adapter.

1/4″ Outer Diameter (OD) Tubing

The first fitting is a quick disconnect fitting for 1/4” OD tubing. All “Instant-Off” and “Master” sandblasters come with this quick disconnect already equipped. On standard units, this fitting can replace the barb fitting (from below).

1/4″ Inner Diameter (ID) Tubing

The second fitting that is included with all Vaniman sandblasters is the barb fitting for 1/4” ID tubing. All standard sandblasters come with this barb fitting attached. On “Instant-Off” and “Master” units, this fitting can replace the quick disconnect (from above). This tubing has to be secured onto the barb using a small hose clamp.

Lock Sleeve Quick Disconnect

The third type of fitting is an 1/8″ to 1/4″ adapter. All Vaniman air-line plumbing parts are standard 1/8″ NPT fittings. The included 1/8″ to 1/4″ adapter can connect a Vaniman unit to a variety of 1/4″ NPT fittings. Quick lock sleeve systems are popular in many industrial workshops. While Vaniman does not carry lock sleeves, we have provided links to products that can be purchased from McMaster-Carr (below).

For 1/4” NPT pipe, use included 1/8” to 1/4” adapter as shown.

McMaster-Carr has several standard quick disconnect hose couplings available:

There are several different standard couplings with “Industrial” being the most common:
