Notes:
• Working pressure ratings are based on using any smooth rubber hose, except chemical, steam, and hot tar.
• Working pressure ratings are based on using Campbell Crimpnology™ products only, and that proper crimping procedures have been followed.
• Working pressure ratings are maximum as listed or the hose rating, whichever is lower.
• Always ensure the coupling/fitting and hose are compatible with the specific product being used. Please refer to the RMA Handbook or contact Campbell Fittings for chemical compatibility with couplings. Check with the hose manufacturer regarding chemical compatibility with the hose.
