Product Details

The Roam Series Gravity Fill Water Inlet keeps your RV adventure-ready with rugged, waterproof protection (IP68/IP69K rated) perfect for regular water refills on longer trips.

Made from drinking water-safe materials that meet NSF/ANSI 61 and WRAS standards, it includes a lockable filler cap, two keys for peace of mind wherever you park.

Designed for easy, spill-free filling with an 18° downward feed that ensures water flows smoothly into the tank, while the built-in breather pipe prevents wasteful overflow. Compatible with a 38 mm (1 ½” ) or 35 mm (1 3/8") rear hose, it fills directly from the front using a garden hose or water container.

A shallow 70.5 mm (2.77") install depth allows flexible placement, and the easy-clean design keeps everything hygienic and maintenance simple.

Built with Scanstrut marine-grade design innovation, the inlet is UV-tested, IP68/IP69K waterproof, and crafted with 316 stainless steel hardware for lasting durability in any environment.

The Roam Series ensures a clean, uniform exterior across your gas, water, power, and more for the perfect uniform finishing touch to your adventure-ready setup.

SCA Testing

The testing standard at Scanstrut is encapsulated by the acronym SCA, which stands for Safe, Certified, and Approved. With over 35 years of experience and expertise in designing products for outdoor use, Scanstrut design products to be able to thrive in the harshest of outdoor environments.

Before any product is released, it must pass through the rigorous testing program which involves assessments in electrical, mechanical, U.V., corrosion, thermal, and waterproof categories. To ensure the highest level of accuracy, testing is conducted both internally and by independent ISO accredited test houses.

This commitment to quality has earned Scanstrut the approval of renowned names such as Mercury Marine, Grady White Boats, Boston Whaler, Winnebago, Airstream and many more. To learn more about the SCA testing program and certifications, get in touch.

On/Off Road Testing

Simulates real-world performance by rigorously testing the product across varied terrains, including roads and off-road trails

Cycle Testing

Simulates extended long-term use by repeatedly opening and closing a lid to replicate mechanical wear over time.

Water Pressure Test

Evaluates the product’s capacity to endure rising internal pressure, ensuring it maintains structural integrity under extreme conditions.

IP Test

Water and dust protection under test laboratory conditions to international IP standards. We test between IPX4 (waterjet) and IP68 (submersion).

Accelerated UV Material Test

We accelerate the effects of UV exposure to replicate our products usage in extreme tropical climates. We do this to ensure parts do not become brittle, discolour or fail over time.

Thermal Chamber Test

Laboratory chamber running from -40°C (-40°F) to +85°C (185°F) and back to -40°C (-40°F) for 120 cycles, this accelerates material ageing to simulate real world environment.

Temperature Chamber Test

Product placed in a laboratory chamber at high temperatures to ensure our products continue to perform as designed.

Corrosion Test

100-hours of a special formula salt spray that simulates accelerated marine environmental effects on the product.

FEA Analysis

Finite Element Analysis, simulates the behaviour of the design in virtual conditions to allow us to optimise the design before prototyping and physical testing.

C Tick

An identification trademark registered to the ACMA indicates that the equipment complies with the relevant EMC standard.

CE / UKCA

Signifies that our products have been assessed to meet high safety, health, and environmental protection requirements.

FCC

A legal requirement to sell any communication device (RF) in the United States of America.

Humidity Chamber Test

Similar to our brutal SCA Thermal Chamber Test, but we’ve added humidity to make it even more punishing.

Material Test

Positive Material Identification (PMI) ensures consistent quality of 316 Stainless Steel and Aluminium products. This controls strength and environmental performance.
