Bronkhorst

Which tube fittings does Bronkhorst recommend for their instruments?

As a standard, we use compression type connections or face seal (VCR/VCO) fittings with BSPP thread on our instruments.

BSPP (British Standard Pipe Parallel) is, as the name suggests, a parallel fitting. The threads are used to hold the two pieces together and not to create a seal. The sealing is done by an elastomeric seal external to the thread. Because the seal is external to the thread there is no danger of debris in the threads being forced into the flow path of the gas. For this reason we do not recommend NPT fittings with PTFE (Teflon) tape sealing.
