Replacement Sewage Tank Wheels

Key Features

• Direct Fit for Thetford SC234 / C200 / C220: Engineered to match OEM dimensions exactly — drop-in replacement with no modification required. Fits the original axle mounting points on all three Thetford cassette tank models.
• Not 3D Printed – Injection Moulded PA6 Nylon: Made from high-quality new virgin PA6 raw material via injection moulding — significantly stronger, more dimensionally accurate, and longer-lasting than 3D printed alternatives that crack and deform under load.
• 304 Stainless Steel Axle: Corrosion-resistant, rust-proof stainless steel axle maintains precise alignment and smooth rotation even after repeated outdoor use in wet and muddy conditions.
• All-Terrain Performance: Suitable for dirt roads, gravel roads, grassy terrain, and concrete — the wide 20 mm wheel width and 90 mm diameter provide stable rolling across all campsite surfaces.
• Low Noise Operation: Silent rolling design — no rattling, no squeaking, no grinding. Wear-resistant PA6 material maintains smooth operation over thousands of roll cycles.
• Strong Load-Bearing Capacity: High-quality PA6 nylon with strong internal rib structure handles the full weight of a loaded Thetford cassette tank without deformation or cracking.
• Lightweight – Only 130 g: The complete wheel set (2 wheels + axle) weighs just 130 g — adds zero meaningful weight to your tank while dramatically improving mobility.

Installation Notes

Remove the existing damaged wheels and axle from your Thetford SC234, C200, or C220 cassette tank. Slide the new 304 stainless axle through the tank’s axle housing. Press the PA6 nylon wheels onto both ends of the axle until they seat securely. No tools required for most installations. Total installation time: under 5 minutes.

Why Replace with Roqify Wheels?

Original Thetford wheels are made from standard plastic that cracks, warps, and seizes after a few seasons of outdoor use — especially in UV-exposed campsite conditions. The PA6 nylon used in these replacement wheels has significantly higher impact resistance, UV stability, and wear resistance than standard PP or ABS plastics. Combined with a 304 stainless axle that won’t rust or corrode, this set will outlast the original wheels by years. And unlike the 3D printed alternatives flooding the market, these are injection moulded to precise tolerances — no layer lines, no weak points, no surprises.
