VELAIR - Through-Hull Water Kit for Air Conditioning 3/4" Ultraflex

Ultraflex VELAIR – 3/4" Bulkhead Kit (Ultraflex catalog number 24684W) is a through-hull set designed for routing hoses and/or rigid pipes of the VELAIR marine air conditioning system through the hull, bulkhead, or partition, ensuring a sealed and corrosion-resistant connection. Bulkhead kits are typically used in installations of air conditioning units/marine seawater circuits on boats and yachts where a stable 3/4" pass-through for cooling hoses (sea water loop), condensate lines, or refrigerant lines in split units is required. This solution facilitates a clean, safe installation in bulkheads of various thicknesses, reduces the risk of hose chafing on edges, and minimizes leaks at the hull-installation interface. The kit is intended for marine environments – components are resistant to saltwater and typical vibrations and oscillations of vessels. Installation involves drilling a hole sized for the 3/4" fitting, inserting the bulkhead body with a seal, and tightening the locknut from the opposite side; then 3/4" hoses are connected using clamps or fittings recommended by the system manufacturer. The kit is recommended as an installation accessory for VELAIR/Ultraflex systems and compatible marine HVAC devices, with size selection matching the nominal diameter of the 3/4" water line.
