Alde Rubber Hose Reducer 22 mm → 16 mm – EPDM Heating System Connector

Alde Rubber Hose Reducer 22 mm → 16 mm – EPDM Heating System Connector

The Alde Rubber Hose Reducer (22 mm to 16 mm) is a genuine connection adaptor designed for use in Alde hydronic central heating systems in caravans and motorhomes. It lets you seamlessly transition between 22 mm and 16 mm hose or pipe diameters, helping adapt pipework where your heating circuit changes size or components require different hose sizes.

Made from durable EPDM rubber, this reducer provides a flexible yet secure joint between different diameter hoses while resisting heat and the glycol fluid used in wet heating loops.

Why Choose This Hose Reducer?

• 🔁 Size Transition – Smoothly connects 22 mm to 16 mm pipework for radiator loops or distribution circuits.

• 🛠 Versatile Use – Ideal for modifying or repairing Alde heating installations where pipe sizes differ.

• 💪 EPDM Rubber Construction – Flexible and robust material that withstands heating fluid and temperature cycling.

• 📏 Standard Length (~70 mm) – Long enough to ensure a stable joint between hose diameters without being bulky.

• 🧰 Easy to Install – Push-fit connection with optional spring clips for secure attachment on caravan/motorhome heating circuits.

Key Features & Specifications

What’s Included

• 1 × Alde Rubber Hose Reducer (22 mm to 16 mm)

Note: Spring clips or hose clips may be required for secure fitting onto pipe ends (sold separately).

How It Works

1. Prepare the pipe ends you need to connect — ensuring the 22 mm and 16 mm hoses are clean and straight.

2. Push the reducer onto the larger diameter hose (22 mm) first, then onto the smaller (16 mm), using hose clips if necessary for a secure seal.

3. Check for alignment and ensure that both ends are seated firmly to avoid leaks once the heating fluid is in circulation.

This reducer is especially useful when parts of your hydronic circuit — for example larger convectors or radiators vs service pump outlets — require different hose sizes.

Who It’s For

• Caravan and motorhome owners performing hydronic heating modifications

• DIY enthusiasts tailoring Alde heating circuits

• Technicians replacing or upgrading pipework transitions

Why Buy This Reducer?

Hydronic systems often combine multiple component sizes — convectors, radiators, expansion tanks and pumps — that use different hose diameters. A genuine Alde hose reducer ensures a reliable transition between 22 mm and 16 mm without the risk of leaks or hose slips, maintaining fluid circulation and performance.
