SEAFLO Bilge Pump Installation Kit, 1-1/2" Hose 4.5 ft Kink-Resistant PVC with 316 Stainless Clamps & 1-1/2" Thru-Hull Fitting

SEAFLO's bilge pump installation kit provides a ready-to-install 1-1/2" (29mm) marine plumbing solution with 4.5 feet of kink-resistant PVC hose, two 316 stainless clamps, and a matching 1-1/2" thru-hull fitting.

Outfitting a bilge pump correctly makes the difference between reliable water removal and recurring maintenance headaches. This all-in-one plumbing kit supplies the hose diameter and hardware commonly required for medium to larger bilge pumps, combining corrosion-resistant metal with a flexible hose engineered for tight routing. Everything is sized to standard marine fittings so you can complete a tidy, secure discharge line without sourcing parts separately.

How does this kit simplify installing a bilge pump?

The kit consolidates the core plumbing components into a single package so you can install a discharge line in fewer steps. With matched sizing between hose and thru-hull fitting, there’s less measuring and fewer compatibility issues during fitting.

• Pre-matched 1-1/2" (29mm) outlet diameter for direct connection to many bilge pumps.
• 4.5 ft of flexible PVC hose minimizes the need for extra couplings or adapters.
• Two 316 stainless clamps provide secure hose-to-barb fastening and corrosion resistance.
• Includes a proper 1-1/2" thru-hull fitting to complete a watertight discharge path.

Will the hose resist kinks and keep water flowing when routed through tight spaces?

The hose is designed with flexibility and internal support that prevent collapse under bends, so flow remains consistent even when routed around stringers or through confined bilge areas. That reduces the risk of partial blockage or reduced pump efficiency caused by pinched tubing.

• Kink-resistant PVC construction maintains cross-section under bend stress.
• 4.5-foot length offers routing options without forcing sharp turns.
• Smooth interior reduces turbulence and debris hang-up.

How durable are the metal parts in a saltwater environment?

The kit uses marine-grade 316 stainless steel for both hose clamps, chosen for enhanced resistance to pitting and corrosion in saltwater compared with standard stainless alloys. The thru-hull fitting is built to hold a secure seal under vibration and temperature changes common on boats.

• 316 stainless clamps resist galvanic corrosion and maintain clamp tension over time.
• Thru-hull fitting shaped to accept hose and clamp for a reliable, watertight connection.
• Materials selected to reduce maintenance and replacement frequency in marine use.

What size bilge pumps and boating situations is this kit suitable for?

The 1-1/2" outlet diameter offers a balance of flow capacity and compatibility, making it well-suited for many medium to larger bilge pumps found on recreational powerboats, sailboats, and small commercial craft. It’s ideal when you need a robust discharge line without stepping up to larger, heavier plumbing.

• Appropriate for bilge pumps requiring a 1-1/2" discharge hose.
• Good fit for installations where 4.5 ft of hose length covers pump to hull run.
• Intended for typical recreational and light commercial marine use.

Who is this for: Boaters, marine technicians, and DIY vessel owners seeking a straightforward, corrosion-resistant plumbing kit for a 1-1/2" bilge pump discharge. If you want a matched hose, robust stainless clamps, and a proper thru-hull fitting in one package—without hunting for individual parts—this SEAFLO kit streamlines the install and helps ensure dependable bilge drainage.
