Inflation Coupling
Seamlessly integrate your AERO plug installations with MTi Group's INFLATION COUPLING, the patented solution designed to enhance efficiency in both underground and open pit operations. This versatile connector ensures secure and straightforward inflation of BLASTBALL™ and BLASTBAG AERO™, adapting to various hose sizes for a perfect fit in any operation.
Live pricing and same-day-ship priority once you're in. Setup takes 60 seconds — we just need to confirm you're a real operation.

Why Inflation Coupling
¼” BSP connection
Standard quarter-inch BSP thread fits your existing air supply fittings.
Why it matters: No adapters or special hardware. Connects straight to your compressor or airline.
AERO, ANFO compatible
Works with BLASTBAG AERO inflation systems and ANFO loading hose setups.
Why it matters: One coupling works across multiple product lines. Simplify your accessory inventory.
Uphole environment use
Designed for overhead use where a secure, leak-free connection is critical.
Why it matters: No drips or disconnects when you're inflating above your head. Stays connected under pressure.
Simple air input
Push-to-connect air input. One hand, one motion.
Why it matters: Fast hookup underground where time and simplicity matter most.
Reliable plug insertion
Machined end seats firmly into the BLASTBAG valve. Positive engagement you can feel.
Why it matters: You know it's connected before you inflate. No wasted air, no partial fills.
Diamond knurl option
Diamond-knurled version available for extra grip with wet or gloved hands.
Why it matters: Maintains a solid grip in the conditions you actually work in. No slipping, no re-grabs.
Built for the bench.

Pick the UGHR when you want a complete air service unit with no assembly. Teflon-lined hose, pneumatic inflator/deflator, gauge to 35 PSI, anodized depth crimps, weighted AB-C coupling on the end. 50 m (164 ft) or 100 ft (30 m) hose options. Plug into mine air via ¼" BSP and you're ready. Working pressure 10 – 300 PSI — covers every BLASTBAG AERO and BLASTBALL spec. Best-in-class for production underground sites running daily air decks.
Pick the Inflation Assembly when you want the same kit as the UGHR but without the reel — three components pre-packaged at a common dropline length. Includes Dropline + Handheld Inflator + Weighted AB-C Coupling. Four lengths: 25 ft, 60 ft, 100 ft, and 50 m. Cheaper than the UGHR, simpler than building from parts, and field-portable.
Pick the Handheld Inflator when you're working benches without service air at the hole, or you need to reposition a bag before final inflation. Stainless steel cage, Nitto fittings, gauge to 36 PSI, rated to 200 PSI max. Inflates and deflates. Pair with any Dropline Hose and AB-C Coupling to build a portable kit.
Pick a Dropline Hose when you need a specific length not covered by the standard kits, or you're replacing the hose on an existing setup. Teflon-lined thermoplastic, designed for repeated tensile loading from lowering inflated bags. Crimps every 5 m / 10 ft tell the operator exactly how deep the bag is. Sizes: 25 ft (5 m), 60 ft (18 m), 50 m (164 ft), 100 ft (30 m). All metals are stainless steel — explosives-compatible.
Pick an Inflation Coupling when you need a replacement, a spare, or a full hose-end rebuild. The AB-C is MTi's patented snap-on connector — pushes onto the bag's air valve to inflate, pulls free under load to leave the inflated bag at depth. Two versions: AB-C Diamond Knurl (02-001, $114) is the coupling alone. The Complete Hose End Replacement (02-024, $409) is the whole end of the dropline — weight, ferrule, tail, nipple, and coupling — ready to swap onto a worn hose.
The air-operated gas bag this kit serves. Compressed air, dual-bladder construction, snap-on AB-C coupling. Two SKUs cover 2.5" to 12.25" (64 – 311 mm). Underground production, air decking, uphole capping. See the BLASTBAGS collection for full positioning, sizing, and case studies.
The wet-hole-rated air-inflated plug this kit also serves. Hermetic bladder with tire-strength nylon webbing. Three SKUs cover 2.5" to 8" (64 – 203 mm). Lower it through water, inflate to seal a breakthrough, crack, or void. See the Stemming Plugs collection for full positioning.
