Leader at Concept Engineers

We are appointed distributors for Leader. Product comes from the works, the warranty is the manufacturer's own, and certification can be arranged at order stage.

We list 289 Leader families, 8 mm to 1050 mm, spanning check & non-return valves, gate valves, globe valves, ball valves and butterfly valves. Follow any range below for its full size and price table.

List prices here are ex-GST and are Leader's own. Where a buyer has agreed rates with us, those rates appear in place of list once they are signed in to the site.

Certification is available against the order for products that carry it. The requirement goes to the works with the order, which is why it needs to be on the enquiry rather than mentioned afterwards.

Anything in the Leader range that is not shown can normally be obtained. Give us the medium, the pressure and the temperature along with the sizes and we will quote it.
