Hi-Flo BlastBall Qwik Coupling:AB-C

MTi GROUPs patented Inflation Coupling was designed for easy quick connection with BLASTBALL, BLASTBAG AERO, and Long Hole Stabilizer products. The coupling is made from a marine grade stainless steel and will not corrode in the harsh mining environment. 

The straight patterned coupling (flat sides) is a tighter fitting, which is used for underwater decking or for small diameter BLASTBALL plugs where there is high backpressure.
