Trelleborg sets Guinness record for the largest O-ring

Tewkesbury, UK – Trelleborg Sealing Solutions has set a new Guinness World Records title for the largest O-ring ever manufactured.

Produced at Trelleborg’s facility in Tewkesbury, the UK, the seal was manufactured using FlexiMold process, which allows the production of giant seamless O-rings, said Trelleborg in a statement 12 July.

To produce the elastomer O-ring, measuring 364 metres in circumference, Trelleborg teamed up with 20 GCSE engineering pupils from Tewkesbury School.

Over a summer school term, the students were coached in various manufacturing disciplines and were involved in the design, costing and production planning of the O-ring.

“This undertaking has not only [been] a lot of fun, but a learning experience for the pupils at Tewkesbury School and our team here too,” said Tony Collingwood, general manager of the Trelleborg Sealing Solutions manufacturing facility in Tewkesbury.

Large O-rings are used across all process industries, including chemical and hydrocarbon, pharmaceutical, and in the electronics industry, in particular the production of flat panel displays applications.

The integrity of the O-ring was independently verified by Artis, an elastomer consultancy based in the UK.

The circumference of the O-Ring was measured by an industrial wire measuring machine and the record was then confirmed by the adjudicator from the Guinness Book of Records.
