Conex reducing connector B Press 18 x 15 mm P524301815000

The Conex reducing connector B Press 18 x 15 mm P524301815000 is a press-fit fitting engineered to connect copper or compatible pipes of different diameters in potable water, heating and domestic plumbing systems. The connector provides a compact stepped reduction from 18 mm to 15 mm and is designed for permanent mechanical joints created with a compatible press tool and pressing jaws. Constructed to meet common plumbing requirements, the B Press geometry ensures consistent deformation and a secure seal when installed according to manufacturer guidelines.

Advantages

This reducing connector delivers a reliable mechanical connection without soldering, brazing or threading, reducing installation time and exposure to heat. Its press-fit design offers consistent joint quality and is suitable for use in confined spaces where a compact stepped reduction is required. The connector is compatible with standard press tools and jaws specified for B Press fittings, providing leak-resistant performance when installed correctly.

Suitable for

• Potable cold and hot water distribution
• Domestic heating systems and radiator connections
• Plumbing repair and retrofit projects requiring a size reduction
• Situations where soldering is impractical or restricted

Key specifications

• Type: Press-fit reducing connector (stepped)
• Material compatibility: Copper and press-compatible plumbing tubing
• Connection sizes: 18 mm to 15 mm
• Installation method: Mechanical press joint using compatible press tool and jaws
• Typical applications: Potable water and heating systems

How to use

Prepare pipe ends by cutting squarely, deburring and ensuring the surfaces are clean and free from contaminants. Slide the connector onto the larger or smaller pipe end as required, ensuring correct insertion depth. Use the appropriate B Press-compatible pressing tool and jaws sized for the connector to perform a single, full press cycle until the correct deformation is achieved. Verify the joint visually and, where applicable, perform a pressure test in accordance with local regulations and installation standards.

Usage recommendations

Use only press tools and jaws approved for B Press fittings and follow local plumbing codes. Avoid using damaged or worn pressing jaws, and confirm pipe material and wall thickness are compatible with press-fit installation. Where systems convey potable water, flush and inspect the system after completing connections and perform a pressure test to confirm leak-free joints.
