Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement part from the 4Drive / Aftermarket range, manufactured to exceed original equipment standards for marine and RV use.
How do I know if it is compatible?
Check your hose internal diameter (ID). This valve features a stepped inlet for 33mm-38mm hoses and a dedicated 38mm (1.5") outlet. If your current hose matches these dimensions, it is compatible.
Can the valve be cleaned if debris gets stuck?
Yes. One of the unique benefits of this Seaflo model is the threaded mid-section. You can simply unscrew the two halves of the valve body to inspect the internal flap and clear any debris without removing the hose connections from the ports.
Note: Please verify your existing hose size and system requirements at 4drive.co.uk before finalizing your purchase.
