Complete 15-foot RV sewer hose kit with Thetford Titan TPE hose, ExtendGrip universal bayonet fittings, Revolve rotating 5-in-1 sewer adapter, 2 end caps, and 2 replacement seals. Virtually uncrushable, extreme temperature resistant. Made in USA. Previously known as Thetford part number 17858.
The Thetford 50329 is the Titan 15-foot premium RV sewer kit — Thetford's flagship complete sewer hose kit, previously known as part number 17858. The Titan line is built around Thetford's proprietary TPE (thermoplastic elastomer) hose material, which provides a meaningfully higher level of puncture and abrasion resistance than standard vinyl sewer hoses and maintains flexibility across a much wider temperature range — it won't stiffen and crack in cold weather or soften dangerously in summer heat.
The kit includes two purpose-designed fittings that address the two most common friction points in the sewer hookup process. The ExtendGrip bayonet fitting has a larger-than-standard surface area, making it easier to grip and connect/disconnect — especially with gloves on. The Revolve 5-in-1 sewer adapter rotates for easy alignment with the dump port and has a handle to keep hands further from the mess during connection. End caps seal both hose ends for storage without drips.

Standard RV sewer hoses use vinyl construction — cost-effective but prone to cracking in cold weather, softening in heat, and puncturing on rough ground. Thetford's Titan TPE hose addresses all three: Cold weather: TPE stays flexible at temperatures where vinyl becomes stiff and brittle — no cracking during winter dumping Abrasion resistance: TPE is substantially tougher than vinyl — resists cuts and punctures from pavement, gravel, and rough dump station pads Crush resistance: The Titan hose is described as virtually uncrushable — drive-over accidents that would ruin a vinyl hose are survivable For full-timers or frequent campers who dump regularly in varied conditions, the TPE material is a meaningful upgrade over economy vinyl hoses.
