SEAFLO Bilge Pump Installation Kit 1" Outlet Hose 4.5 ft Kink-Free PVC with 316 Stainless Clamps

SEAFLO's bilge pump installation kit is a ready-to-fit plumbing set that includes a 4.5-foot 1" kink-free PVC hose, two 316 stainless-steel hose clamps, and a 1" thru-hull fitting for reliable bilge discharge.

When installing or replacing bilge plumbing on a small to mid-size boat, you want components that resist corrosion, avoid kinks, and match common pump outlets. This kit provides purpose-selected parts that simplify routing, secure hose connections, and offer a clean exit through the hull — all sized to the industry-standard 1" outlet diameter. The pieces are suited for freshwater and saltwater use and are intended for use with most 1" bilge pumps and discharge setups.

How does this kit make bilge plumbing quicker to install?

The kit groups the hose, clamps, and thru-hull fitting so you don’t have to source matching parts separately. The 4.5-foot hose is long enough for typical bilge runs, while the clamps and fitting match the 1" diameter of most pumps for a straightforward connection. That reduces guesswork and time during installation.

• Pre-sized 1" hose for direct pump connection
• Two corrosion-resistant 316 stainless clamps included
• 4.5 ft length suitable for common bilge routing
• Thru-hull fitting for a neat exterior discharge point

Will the hose keep water flowing if routed through tight spaces?

The included PVC hose is engineered to stay flexible without kinking, preserving internal diameter and flow even when bent. That helps prevent restrictions that can reduce pump performance or trap debris. It’s a practical choice when you need to snake plumbing through cramped engine bays or bulkhead areas.

• Kink-resistant PVC retains full bore under bends
• Flexible enough to navigate tight engine compartments
• Maintains steady water evacuation without pinching

Are the clamps and fitting suitable for saltwater environments?

The two hose clamps are stamped 316 stainless steel, a grade chosen for superior resistance to corrosion from saltwater exposure. The thru-hull fitting is designed for marine discharge applications and provides a secure passage through the hull when fitted and sealed correctly. Together they help minimize corrosion-related failures and leaks when installed per marine best practices.

• 316 stainless clamps resist rust and pitting
• Thru-hull fitting sized for 1" discharge ports
• Durable materials selected for marine conditions

What fittings and sizes should I expect to work with this kit?

Everything in the kit is standardized around a 1" outlet diameter, which matches many common bilge pumps and discharge nipples. The hose clamps are adjustable to securely grip the hose at pump and thru-hull connections. If your pump or existing plumbing uses a different diameter, an adapter or alternative hose will be required.

• 1" internal hose diameter for direct pump compatibility
• Adjustable 316 clamps for tight seals
• Thru-hull fitting matched to the 1" hose size

Who is this for: This SEAFLO kit is aimed at boat owners, marine technicians, and DIYers replacing or installing bilge pump plumbing on small to medium vessels. It’s especially useful when you need corrosion-resistant clamps, a flexible kink-free hose for confined routing, and a matched thru-hull discharge — all supplied together to simplify a professional-looking installation.
