Advanced contamination protection and secure locking Specially designed locking mechanism prevents ingress of dirt and foreign particles and stops accidental unlocking during travel. Keeps onboard water clean and safe, reducing the risk of contamination and unscheduled maintenance. Flow-optimized inlet for fast, splash-protected filling Precision-molded inlet with integrated gutter guidance directs incoming water and minimizes splashing and overflow. Speeds up tank filling, reduces cleaning effort, and simplifies everyday water handling in motorhome and camper-van use. Temperature compensation to preserve seals and durability Engineered material behavior automatically compensates for thermal expansion differences, preventing stress cracks. Maintains sealing function across temperature changes for reliable long-term performance. Dual independent key backup for uninterrupted access Supplied with two separate keys to reduce the impact of a lost key and ensure continued, trouble-free operation. Thoughtful backup concept tailored for water connections on camping vehicles. Function and compatibility Designed specifically for water inlets and connectors on motorhomes, camper vans, and other recreational vehicles. Functions: secure locking, splash-protected filling, thermal-stable sealing, and keyed access with backup. Material: specialized formulation engineered for thermal compensation and long-term sealing performance. Practical benefits at a glance Keeps fresh water uncontaminated and accessible while driving. Lowers cleaning and maintenance time thanks to splash reduction and reliable seals. Reduces downtime caused by key loss with two independent keys. Offers consistent sealing performance despite temperature fluctuations encountered in outdoor use. Typical use scenarios Filling the fresh-water tank at a campsite: fast, splash-protected inlet reduces mess and cleanup after refilling. Travel on rough roads: secure lock prevents accidental opening and contamination while the vehicle is in motion. Cold-to-warm seasonal changes: material compensation prevents seal failure and cracking during large temperature swings. What makes it stand out Combination of a contamination-blocking lock, flow-optimized inlet, thermal compensation material, and dual-key backup—specifically engineered for the demands of camping vehicles. Practical design focused on reliable daily operation, reduced maintenance, and secure water management on the road.
