Trident Marine 1" VAC XHD Sanitation Hose - Hard PVC Helix - White - Sold by the Foot

The Trident Marine 1" VAC XHD Sanitation Hose is the backbone of any responsible vessel's waste management system. Built for marine heads and blackwater applications, this hard PVC helix hose is engineered to handle the demands of saltwater and freshwater boating environments alike. Whether you're cruising coastal waters or anchored in remote coves, proper sanitation hose routing and replacement is non-negotiable for both EPA compliance and the health of your vessel's systems. This hose delivers the durability and reliability that experienced boaters demand when managing waste systems offshore.

Trident Marine's XHD (Extra Heavy Duty) construction features a reinforced hard PVC helix core that resists kinks, crushing, and UV degradation—critical factors when hose runs navigate tight engine compartments or sit exposed on deck. The 1-inch interior diameter accommodates standard marine sanitation discharge flows without backpressure, while the white finish simplifies identification during inspections and maintenance. The helix support structure maintains hose integrity under vacuum and pressure cycles, preventing the collapse that can trap waste and create blockages. This material composition ensures long service life even in harsh marine conditions, reducing the frequency of mid-season replacements that cost time and money.

Boaters upgrading or repairing existing sanitation systems will appreciate that this hose is sold by the foot, allowing you to purchase exactly what your vessel's layout requires—no waste, no storage headaches. Install it between your marine head, holding tank, and through-hull discharge fitting using standard marine-grade hose clamps rated for saltwater service. The 1-inch diameter compatibility makes it ideal for single or dual-head installations on cruisers, motorsailers, and trawlers where reliable waste containment directly impacts onboard comfort and resale value. Measure your existing runs carefully and account for necessary bends and rise angles to prevent siphoning and ensure gravity-assisted drainage.
