SeaMule SM-QCWFSS12 Quick Connect Water Fitting 316 Stainless Steel Thru-Hull

The SeaMule SM-QCWFSS12 Quick Connect Water Fitting is a solid 316 marine-grade stainless steel thru-hull fitting that brings quick-connect convenience to your boat's freshwater inlets and outlets. Designed as a direct replacement for standard Perko-style water inlets, it converts any threaded onboard water inlet or outlet — including transom flush ports, washdowns, and general water inlets — into a fast, tool-free quick-connect connection point.

Built around an industrial-grade double O-ring seal, this fitting delivers an airtight, pressurized-performance connection every time. The included locking safety cap keeps the port protected when not in use and prevents accidental disconnection underway or in storage. A dual barb kit (1/2" and 3/8" threaded barbs) lets you match the fitting to your boat's existing internal hose diameter.

Key Features:

• Solid 316 Marine-Grade Stainless Steel construction for maximum corrosion resistance in harsh saltwater environments
• Universal Male Quick Connect with locking safety cap and tethered chain
• Industrial-Grade Double O-Ring Seal for airtight, pressurized performance
• Standard 3-Hole Bolt Pattern — matches the footprint of most common marine water inlets
• Dual Barb Kit Included — choose 1/2" or 3/8" threaded barb to suit your internal hose diameter
• 316 SS Mounting Screws and Rubber Mounting Gasket included for a complete installation
• Multi-Use Design — suitable for transom flush ports, washdowns, or any onboard water inlet/outlet

What's Included:

• Baseplate with quick-connect tip and cap with chain
• Female adapter with internal 316 SS spring
• 1/2" threaded barb
• 3/8" threaded barb

Note: Marine-grade hose clamps are not included. Use the 1/2" or 3/8" barb to match your boat's internal hose diameter. Internal clearance may vary depending on your boat's original plumbing configuration.
