Blast-One Weekly Tips
Tip #39
Don't lose pressure due to undersized couplings

Use Mega Max Couplings to achieve an unrestricted air flow

All hoses with an ID greater than 1 1/4" (32mm) should have Mega Max couplings fitted to reduce air flow restrictions.  The advantage in using large bore hose fittings is the reduction of gasket and coupling wear.  Mega Max coupling have larger coupling gaskets with larger bores.

A rule of thumb is any nozzle 1/2" or above - use Mega Max couplings.  In this case you would require 400 + cfm compressor for 100psi at the nozzle.  An unrestricted air flow produces less pressure loss, with increased performance.
