20mm PVC Marine/RV Drain Hose

MF20 is the smallest drain hose in the range, a 20 mm bore that suits a caravan basin waste, a galley sink outlet or the discharge from a small bilge or pond pump. The wall is black PVC with a rigid PVC helix moulded into it, so it bends around a bulkhead or through a chassis rail without folding flat, while the bore stays smooth enough that soap scum and grit keep moving. Outside diameter is 24.7 mm and working pressure is 0.2 MPa (29 psi) at 20°C.

Key features

• 20 mm nominal inside diameter, 24.7 mm outside diameter
• Black PVC hose with a rigid PVC helix
• Smooth bore, so waste does not catch on the helix
• Working pressure 0.2 MPa (29 psi) at 20°C
• Operating temperature -5°C to +60°C
• Conforms to AS/NZS 2070 for plastics in food contact
• Cut 2 m, 5 m, 8 m, 10 m and 15 m, or a 20 m coil

Applications

• Caravan basin and hand wash drains
• Galley sink wastes on small craft
• Small bilge and pond pump discharge
• Lightweight air seeder hose
• Low voltage cable conduit through a chassis

Compatibility and fitting

• Push over a 20 mm hose tail or skin fitting and clamp; see hose clamps and skin fittings
• Low pressure only at 29 psi; for a pumped grey water line use purple sullage hose
• Larger bores are on PVC marine and RV drain hose

Will 20 mm hose fit a 20 mm skin fitting?

Yes, provided the fitting is sized by bore like the hose. The 24.7 mm outside diameter is what matters for the hole and the clamp, so check clearance where the hose passes through a bulkhead.
