Sandblast Nozzle Holder - Aluminum, 1-1/4 in NPSM Thread, for 3/4, 1 and 1-1/4 in Blast Hose
Aluminum sandblast nozzle holders, the fitting that goes on the operator end of the blast hose and accepts the threaded end of a blast nozzle. Same sleeve-type body as the standard hose-end coupling, but instead of a crowfoot lug end it carries a 1-1/4 in NPSM straight thread for the nozzle.
The holder slips over the outside diameter of the hose and is fixed with wood screws through countersunk holes, so the screw heads sit flush and will not catch as the hose is dragged across steel or concrete. An internal corkscrew ridge helps twist the holder onto the hose and resists blow-back under pressure.
Sizes
- NH1A: for 3/4 in ID blast hose, 1-1/2 in OD
- NH2A: for 1 in ID blast hose, 1-7/8 in OD
- NH3A: for 1-1/4 in ID blast hose, 2-5/32 in OD
One nozzle thread across every size
All three sizes use the same 1-1/4 in to 11.5 NPSM nozzle thread, which is the common contractor blast nozzle thread. The hose size changes, the nozzle thread does not, so the same nozzles move between a 3/4 in and a 1-1/4 in hose without a new inventory of nozzles. Match the holder to your hose OD and the nozzle will fit whichever one you pick.
Key specifications
- Material: aluminum
- Nozzle thread: 1-1/4 in to 11.5 NPSM, all sizes
- Type: sleeve-type hose end, secured with wood screws
- Hose sizes covered: 3/4 in, 1 in and 1-1/4 in ID blast hose
Fitting and safety
Cut the hose square, work the holder on against the internal ridge until the hose butts up inside the sleeve, then drive the screws through the countersunk holes into the hose wall. Thread the nozzle in by hand against its washer. Never point a blast nozzle at anyone, never break a connection with the pot pressurised, and inspect the holder for wear at the throat, because abrasive cuts the inside of a holder long before anything shows on the outside.

Fit the matching aluminum two-lug hose-end coupling at the other end of the hose and the threaded pot coupling at the blast machine, and keep the hose itself in the same size. Brass versions of this pattern exist where a non-sparking fitting is required. Ask us if that is what the job calls for.
