The Primaflow Washing Machine Outlet Hose Rubber Collar is an essential plumbing component for homeowners and contractors looking to create a watertight, professional seal where a washing machine waste hose meets a soil pipe stack. It provides a secure, vibration-resistant connection that prevents leaks and odors, making it ideal for laundry room installations. The main caveat is that it is specifically sized for 19mm hoses, so users must verify their hose diameter before installation to ensure a proper fit.

No, this collar is precision-engineered for 19mm hoses. Using a larger hose will prevent a proper seal and may damage the rubber.
The material is robust, but prolonged exposure to direct UV sunlight may cause the rubber to harden over time. It is best used for indoor utility areas.
The collar is designed to provide a compression seal on its own. However, if the hole in the soil pipe is irregular, a small amount of sanitary silicone sealant may be used around the outer flange.
No, this is a sealing collar for waste hoses. It does not contain a check valve to prevent backflow.
Measure the penetration in your soil pipe. The collar should fit snugly into the hole without requiring force that deforms the rubber.
Ensure the hose is pushed deep enough into the soil pipe and consider using a small hose clamp if vibration is excessive.
Check that the soil pipe hole is not too large for the collar and ensure the collar is seated completely flush against the pipe wall.
Apply a small amount of silicone-based lubricant or washing-up liquid to the tip of the hose to help it slide through the rubber aperture.
To install, ensure your soil pipe has an appropriately sized hole drilled or prepared. Gently push the rubber collar into the opening until it sits flush against the pipe surface. Once positioned, feed your 19mm washing machine waste hose through the center aperture.
Compatibility: This product is strictly for 19mm waste hoses and standard soil pipe penetrations. Do not attempt to stretch the collar for larger diameter hoses as this will compromise the seal.
Care Instructions: Periodically inspect the collar for signs of cracking or hardening. If you notice leaks during a drain cycle, check that the hose has not slipped or become kinked. Keep the surrounding area dry to prevent mold growth between the collar and the pipe surface.
