The Elcometer Compressed Air Bull Hose Gaskets in leather (part numbers MT30515-5, MT30515-6, MT30515-7 and MT30515-8) are sealing washers used to seal nut and tail air couplings on compressed air bull hose. A poorly sealed coupling leaks air and reduces the pressure available at the blast nozzle, so a correctly fitted gasket helps maintain a tight, efficient connection between hose lengths.

The leather washers are supplied in packs of four and are sized to match the bore of the bull hose coupling. The MT30515-5 fits 25mm couplings, the MT30515-6 fits 32mm, the MT30515-7 fits 38mm and the MT30515-8 fits 51mm. All four are universal part numbers.

These gaskets are consumable items used in abrasive blasting and surface preparation work across coatings, corrosion and marine operations, and are supplied by BAMR, South Africa's authorised Elcometer distributor.
