Brass hose barbs for air systems

The Midwest Fastener 66511 pack contains four brass hose barbs designed to join flexible plastic or rubber tubing in air compressor and vacuum pump setups. Barb rings on each cylindrical piece allow a simple push connection that resists accidental disconnection. The fittings suit workshops and automotive jobs where quick, secure hose attachment is needed.

Steady sealing under continuous pressure

Brass construction resists corrosion from moisture and oil vapour commonly present in compressed-air lines. The barb profile maintains grip when the system cycles between loaded and unloaded states, reducing the chance of leaks during extended runs. No moving parts or seals are included, so performance depends on proper hose selection and clamp use.

Low thermal impact and no noise

The fittings add no electrical draw, generate no audible noise and do not alter the thermal profile of the compressor or pump. They operate passively across the temperature range of typical shop air systems. California Proposition 65 notices apply because the brass alloy contains listed chemicals.

Questions about this item

Do the 66511 brass hose barbs generate any noise or heat when used continuously on an air line?

Brass hose barbs are passive fittings with no moving parts, so they produce no noise, heat or power draw during all-day operation.

What thread sealant or tape must I already have to install the 3/8" male pipe threads on the 66511 barbs?

You will need PTFE thread tape or pipe dope to seal the 3/8" male pipe threads against the compressor or tool port.

Will the 66511 barbs connect directly to the rubber hose on my older compressor without an adapter?

The barb end pushes into standard 3/8" ID rubber or plastic tubing, so it fits older hoses of that bore without extra adapters.
