Tired of taping together your hose runs?

Each Link 2 Link kit includes two magnetic coupler halves that install onto separate sections of your heater ducting. Once attached, the hoses can be connected or separated at the magnetic interface instead of repeatedly loosening clamps or forcing ducting over an adapter.

Manufactured from carbon-fiber-reinforced polycarbonate, the couplers are lightweight, durable, and designed for use around heated ducting.

Available for both 3-inch and 4-inch hose sizes, Link 2 Link is built for portable heater setups, campers, shelters, workshops, and longer temporary heat runs.

Don't have a 4" hose adapter for your heater? See the store for adapters.

Each kit includes:
• 2 magnetic coupler halves

Variations: Select at Checkout
• for 3" hose (heater OEM)
• for 4" hose (aetherium ecosystem upgrade)

Hose clamps not included
Link 2 Link is part of the Aetherium Vent Link, Tent Link, and Mag Link ecosystem.
