Low Pressure Fittings, Round

These superior round fittings are made from accurate fitting patterns electrically cut with good shouldered seams.


These very strong seams are designed for low-pressure air systems and may be used ABOVE ground or UNDER ground when embedded in concrete. Couplings are built into the ends of the fittings.

Types of Fittings:

All standard fitting sizes and shapes are available. 90, 60, 45 and 30 degree elbows are standard. Other angles are available on special order. Tees, lateral (45 degree branch), reducers, and couplings are standard. For elbows, a centerline radius of one times the diameter is standard. 1-1/2 times the diameter (full radius) and 2 times the diameter (long radius) are available. We can also make other size radii and other fittings as specified.

Sizes and Gauges:

4” – 10” are available in 1 inch increments
12” – 64” are available in 2 inch increments

ADMP’s low pressure fittings will meet or exceed the gauges listed in the SMACNA 2005, 3rd edition manual.

Fittings are machine cut on our State-of-the-Art Vulcan Plasma table, assuring manufacturing tolerance consistency.
