Got two pieces of 3-inch hose to connect? This aluminum splice connector does the job. It’s basically a short sleeve you thread each hose end onto, and the aluminum construction is crushproof, so it holds up better than plastic. Simple, no-frills part for extending or repairing ducting, venting, or other hose runs. Lightweight (about 0.67 lb) and corrosion-resistant. Just slide it on and clamp if needed. Handy for shop, HVAC, or any DIY hose project.
