The two main problems that contractors do not want at a job site are accidents, and equipment deteriorating too quickly.
Not too long ago, we had a customer call in with a problem, his blast hoses were wearing out right near the couplings and he needed to know why. If the coupling is not fitted properly, the hose has been known to wear out in that spot because the pressure can escape.
SIX STEPS NEEDED FOR THE CORRECT FITTING OF THE BLAST HOSE TO THE COUPLING.
These six steps will assure safety for blasters, and length in the life of the blast hoses.
Be sure that the Gasket Bore (A1) and the Flange Bore (A2) are equal or bigger than the Blast Hose Bore (A3). This will give the couplings a longer working time and keep from leaving the gasket unsound and exposed to leaks. Use Mega Max Large Bore Couplings for any hose bore bigger than 1 1/4″ (32mm).
When completed, if step 2 was used, wait until the sealant has completely cured. This is usually 24 hours. Once completed, pressurize the hose and use the soapy water method to find any air leaks. Remove the coupling and refit the hose if, at any time, there is an air leak.
DISCLAIMER: Neither BlastOne, nor its associated companies, are liable if these instructions are followed and an accidental coupling detachment occurs. These instructions are provided as a guide only.
