Valterra RV Drain Hose EZ Coupler Valve Adapter — Red, Tool-Free Bayonet Connection for Leak-Resistant Sewage Hookup

The Valterra F02-3101 EZ Coupler Valve Adapter converts a standard RV drain hose into a compact, tool-free valve connection for cleaner, leak-resistant wastewater handling.

Designed for campers, travel trailers and motorhomes, this bright red adapter screws onto your existing sewer hose to create a bayonet-style valve interface that simplifies hookup, storage and transfer. Its self-threading geometry and durable construction let you attach and detach quickly without clamps or special tools. When paired with the separate Valterra F02-3108 Bayonet Adapter, it extends your sewer line and creates a secure, standardized connection point that reduces mess and fumbling at dump stations.

How does the EZ Coupler make hooking up my RV sewer hose faster?

The coupler screws directly onto your current drain hose and converts the hose end into a bayonet valve so you can lock and release quickly. Installation requires only a twist—no clamps or screwdrivers—so routine hookups take less time and effort.

• Self-threading fit for tool-free attachment
• Four bayonet lugs for fast, secure locking
• Compact profile reduces bulk while in storage

Will this adapter stop leaks and drips during use?

The adapter’s self-threading design and precision fit reduce the chance of leaks when properly installed. It’s not a replacement for damaged hose ends, but it provides a tighter seal than many temporary clamp solutions.

• Tightly engineered threads minimize seepage
• Bayonet connection creates a secure, wobble-resistant joint
• Durable materials maintain fit over repeated use

Can I extend my sewer line with other Valterra parts?

Yes — the F02-3101 is designed to work with Valterra bayonet components. Adding the F02-3108 Bayonet Adapter (sold separately) lets you create a longer, modular sewer line using standardized bayonet fittings for reliable connections.

• Compatible with Valterra bayonet adapters and extensions
• Enables modular assembly for custom hose lengths
• Quick-connect style reduces time at dump stations

How easy is it to store and transport this adapter when not in use?

The adapter’s compact dimensions and lightweight build make it simple to tuck into an RV storage compartment or sewer hose tote. Its bright red color also helps you locate it quickly among other gear.

• Small form factor fits most storage bins
• Lightweight plastic construction won’t add significant weight
• High-visibility color reduces search time during setup

Who is this for: The Valterra F02-3101 EZ Coupler Valve Adapter is ideal for RV owners who want a cleaner, faster way to manage their sewer hose connections. It suits weekend campers, extended-travel RVers and anyone who prefers modular bayonet fittings over traditional clamp-and-screw assemblies. If you already use Valterra bayonet parts or want a compact, tool-free upgrade to minimize drips and simplify hookups, this adapter is a practical addition to your wastewater kit.
