Product overview

What it does, and where it fits.

When a reactor has a curved end nozzle, this adaptor is used as an interface spacer to connect the glass or the bellow with the reactor. A curved nozzle gives nothing flat for a glass end to seal against, and the adaptor plate provides that face.

It is a flat metal ring with a rubber cushion, enveloped with PTFE, to provide ideal sealing. The metal gives the plate its stiffness, the rubber cushion lets it conform to the curved nozzle, and the PTFE envelope means only PTFE comes into contact with the process fluid.

The range covers DN 25 to DN 300 in eight catalogue references, with plate thickness increasing from 10 mm to 15 mm as bore increases.

FAQ

Questions we are asked about this item.

When the reactor nozzle is curved rather than flat. There is then no face for the glass end or bellow to seal against, and the plate provides one.

PTFE only. The metal ring and the rubber cushion are fully enveloped in PTFE, so neither reaches the process.

It lets the plate conform to the curve of the nozzle and take up the irregularity, so the seal is even all the way round rather than bearing on two high spots.
