Media Blast Couplings- Hose Couplings
We supply quality sandblasting hose couplings in many sizes, styles and materials. Standard couplings may be available in aluminum, brass, nylon or plated iron. Full port blast hose couplings are made of aluminum or brass. Full port couplings are extra large and will not interchange with standard sizes. Tank couplings (threaded couplings) are available in standard and full port. Nozzle holders are standard NPS thread or 50 mm. Use the size chart to determine your coupling based on the hose ID and OD, gasket ID, and thread size.
