What is the JCA04 used for?

It connects 6 inch clay or saltglaze underground pipes to 160mm PVC-U systems.

Can it be used on older clay systems?

Yes, the flexible coupling compensates for surface irregularities in older pipework.

Will this adaptor fit Victorian clay pipes that may have irregular surfaces?

Yes, the flexible EPDM rubber construction accommodates minor surface irregularities and slight variations in pipe wall thickness commonly found in older clay drainage systems.

Do I need to cut the clay pipe to a specific length before fitting this adaptor?

The clay pipe should be cut cleanly and squarely, with any rough edges smoothed to prevent damage to the rubber seal. Ensure there's adequate straight pipe length for the coupling to grip properly.

How tight should I make the stainless steel clamps on the JCA04?

Tighten the clamps firmly but avoid over-tightening which could damage the rubber or distort the pipe. The clamps should compress the rubber evenly to create a watertight seal without crushing.

Can this adaptor handle the different external diameters between old clay and new plastic pipes?

Yes, this coupling is specifically designed to accommodate the diameter differences between traditional 6-inch clay pipes and modern 160mm plastic systems whilst maintaining a secure connection.

Is the JCA04 suitable for underground installation below ground level?

Yes, the EPDM rubber and stainless steel construction makes it suitable for direct burial in underground drainage applications where it will be permanently below ground level.

What's the maximum depth this adaptor can be installed at?

The adaptor can be installed at standard domestic drainage depths, but ensure adequate bedding and backfill support as the flexible coupling cannot bear structural loads like rigid pipe joints.

Will this coupling work with saltglaze pipes as well as standard clay?

Yes, the JCA04 is compatible with both traditional clay and saltglaze pipes of 6-inch diameter, as the flexible rubber seal adapts to the surface characteristics of either material.

The JCA04 6" Clay to 6" Plastic Adaptor provides a reliable and watertight connection between traditional 6-inch (150mm) clay or saltglaze underground pipes and modern PVC-U plastic systems.

Made from flexible EPDM rubber with stainless steel clamping bands, this coupling ensures a tight seal and accommodates minor surface irregularities or diameter variations between dissimilar pipe materials.

Ideal for renovation, extension, or repair projects where older clay drains must connect seamlessly to newer 160mm plastic systems.

Compatible with FloPlast and other standard underground drainage systems.
