3/4″ Air Supply Hose for Abrasive Blasting
This is the air supply hose for abrasive blasting setups that run smaller pots. It carries compressed air from your compressor to the blast pot, and works as a pusher line from the pot’s inlet to the metering valve. It’s Continental’s Frontier 200 hose: EPDM rubber rated to 200 PSI, with a tube that tolerates the light oil mist from air tool lubricators.
What Size Air Hose Do You Need for Sandblasting?
The common rule is an air supply hose with an inside diameter three to four times the nozzle orifice. That makes 3/4″ a fit for small pots with up to 3/4″ piping and smaller nozzles. For larger nozzles or long runs, step up to 1″ or bigger — a 3/4″ hose loses far more pressure.
| Hose ID | Pressure Loss | Production Loss |
|---|---|---|
| 3/4″ | 11.1 PSI | 16.6% |
| 1″ | 2.4 PSI | 3.6% |
| 1-1/4″ | 0.7 PSI | 1.0% |
| 1-1/2″ | 0.2 PSI | 0.3% |
Based on 100 PSI at 150 CFM through 50 ft of hose. Keep runs as short as possible either way.

Frequently Asked Questions
Can I use this hose to carry abrasive?
No. It’s an air supply hose for abrasive blasting setups — the compressor-to-pot line and pusher line. Use blast hose from the pot to the nozzle.
What size air hose do I need for my blast pot?
When choosing an air supply hose for abrasive blasting, a common rule is three to four times your nozzle orifice. 3/4″ suits small pots and nozzles; larger setups should use 1″ or bigger to avoid pressure loss.
What fittings does it take?
2-lug hose ends and two-bolt clamps, not 4-lug fittings.
What lengths are available?
5, 10, 25, 50 and 100 ft.
Is it oil resistant?
It tolerates light oil mist from air tool lubricators, but it is not for petroleum products.
