محول مخروطي Infinity Tools 4" × 2-1/4"

I was pleasantly surprised how well this adapter stays put on my dust collector hose without any tape or clamps. The taper fits tightly and makes switching between the shop vac and the larger line quick.

Finally, a way to use my shop vac hose with my bigger 4" dust collection pipe without duct tape. The taper fits snugly and holds tight even when the hose is under tension.

I'd been fighting a gap between my shop vac hose and the 4" line for months, and this taper adapter finally sealed it up. The 2-1/4" end grips the vac hose snugly with no tape needed, and the fit on the 4" side is solid. Wish I'd grabbed one sooner.
