We have a Semco sealant gun similar to this model that needed an air hose. The hoses attach to the gun with a small AN2 flare fitting (hard to fabricate with common readily available hardware and $65-$135 Depending on length with a back order wait time that was several weeks). This unit looked like the Semco, so we took a chance and ordered one thinking it might have an air line we could use and have a bonus backup “cheap knockoff” gun for the price of a Semco air line. After receiving the gun 3 days after placing the order, I have to admit that I’m surprised and impressed. The gun is clearly a well executed copy of the Semco with the only obvious difference being that the protective housing surrounding the valve lever is cast aluminum for this model vs high impact plastic for the Semco. The parts interchange...including the air line. This gun was made in Taiwan, our Semco is USA made (which we feel is an important consideration). There’s not much to these guns and I’ve not understood the high price Semco has demanded. This is a well made, much less expensive alternative. Time will tell but it looks like it would hold up as well as the Semco.

Maybe OK for occasional use or spare. The Bracket that the side pins lock in to is very soft steel. Tightening the knob can easily distort this bracket. Over time the unit starts to leak and the tendency is to overtighten the knob causing the leakage to get worse.
