What is a hose sealing sleeve used for?

A hose sealing sleeve is used to create a watertight connection between a convoluted waste hose and a caravan plumbing fitting, helping prevent leaks in grey water systems.

What size hose does this fit?

This sleeve is designed to fit standard 28mm caravan waste hoses, with an internal diameter of approximately 28.5mm for a snug seal.

Where is it used in a caravan?

It is typically used in the waste water system, connecting the sink or shower outlet hose to rigid pipe fittings or external waste outlets.

Does it stop leaks?

Yes, the main purpose of the sealing sleeve is to prevent leaks by forming a tight seal between the hose and fitting.

What material is it made from?

It is made from Santoprene, a flexible and durable rubber-like material that resists wear, water, and mild chemicals.

Is it easy to install?

Yes, it is a simple push-fit installation. The sleeve is fitted onto the end of the hose and then connected to the waste fitting.

Can it be reused?

In most cases, yes—if the sleeve remains in good condition and hasn’t hardened or cracked, it can be reused when disconnecting hoses.

Is this required for self-containment compliance?

While small, this component plays an important role in ensuring leak-free plumbing, which is essential for meeting self-containment requirements.

Can it be used with other pipe sizes?

This specific sleeve is designed for 28mm systems. Using it with different sizes may result in poor sealing or leaks.

Why is this part important?

Without a proper sealing sleeve, connections between flexible hose and fittings can leak, leading to water loss, odours, and potential compliance issues in caravan systems.
