Safety-minded materials and lockable security

Healthy material: injection-molded with food-grade polypropylene to help ensure safe use around drinking water, paired with a lockable cap and two included keys for added protection. This setup gives you control over when the hatch is opened, helping reduce accidental exposure to the interior of your water system.

• Food-grade PP construction emphasizes safety and durability
• Locking cap with two keys provides peace of mind during travel and storage

Fast, clean filling at the inlet

Convenient water filling is supported by a bayonet connection and a 75-degree inlet angle, designed to minimize overflow and improve ease of access. A 39 mm large diameter opening helps speed up the refill process so you can get back to your adventure sooner.

• Bayonet coupling reduces spill risk during connection
• 75-degree inlet angle for easier access in tight spots
• 39 mm opening accelerates filling and reduces wait time

Leak prevention and weather-resistance

The spring mechanism works with a sealing ring to minimize water leakage and resist rain intrusion after opening the cover. This combination enhances reliability and keeps the rest of your water system dry and protected.

• Spring and sealing ring provide tight, leak-proof performance
• Rainwater intrusion prevention helps maintain dry exterior components

Safety-forward design to reduce splashback

Anti-backspray design includes ventilation holes that help prevent water from splashing back during filling, contributing to a safer, more comfortable filling process.

• Ventilation minimizes splashback during operation
• Designed with RV use in mind for practical, everyday life on the road

Look and fit

The hatch features an industrial arc texture and clearly marked nozzle indicators, giving a neat, understated look that blends with most RV exteriors while maintaining clear identification for quick use.

• Arc-pattern exterior offers a modern, understated appearance
• Clear nozzle markings simplify operation

Real-world use scenarios

• Fill sessions at campgrounds where speed and simplicity matter, thanks to the large inlet.
• Travelers who value security can rely on the double-key lock for added access control.
• Rugged outdoor environments benefit from a durable, leak-resistant seal and weather protection.
