6 Best RV Sewer Hose Extension in 2026: A Practical RV Guide

This OUTPRIZE extension adds 15 feet of 24 mil TPE hose with an inner steel wire, pre-attached swivel fittings and two storage caps. Packed length is listed at 5.4 feet.

It is the longest true extension in the group and costs less than the SheeChung kit. Compared with the 5 foot and 3 foot OUTPRIZE sections, it gives the most reach for the least cost per foot.

A solid choice for owners of OUTPRIZE or Camco 3 inch hoses.

SheeChung's 15 foot kit pairs a 24 mil TPE hose that recovers from crushing with four-prong swivel bayonets and a clear 90 degree adapter for 3 inch slip and threaded pipes. It can serve as a standalone hose or a long extension.

That makes it the pick when you want a hose that stands on its own.

The OUTPRIZE 5 foot extension uses the same 24 mil TPE wall with an inner wire and swivel fittings on each end. Two storage caps come with it, and a 5 foot hose compresses to 2.5 feet.

It is far cheaper than the 15 foot option and covers small gaps. The compressed length is the shortest of the longer sections, so it fits in a small bin.

The OUTPRIZE 3 foot extension has a 24 mil TPE wall, inner wire, swivel fittings and two caps. A 3 foot section compresses to 1.7 feet.

It is the shortest extension and costs less than the 5 foot. The tiny pack size makes it the easiest to stash.

This second 3 foot OUTPRIZE listing repeats the 24 mil TPE build, inner steel wire and two storage caps. The price equals the first 3 foot version.

It is an alternate listing for the same item class. Buying two covers a 6 foot gap with two joints.

This generic sewer drain pipe is a lightweight corrugated tube with multi-layer sealed connections. It is listed for 28 to 42 mm drainage ports and no-tool installation.

It is the lowest priced item and is aimed at a different port size than the 3 inch bayonet hoses above. It stands out as the lightest and cheapest.
