Leaking compressed air components and Loctite 577

The arrival of the Tormach PCNC440 demanded a review of my compressed air infrastructure.   I have Bambi 24V pot belly compressor which previously only fed a dust off blower.   In addition to this, the compressor now has to feed the new Tormach power drawbar and the Fog Buster coolant system.

To aid distribution I sourced locally a 4 port manifold with an in and pass through in line.   This gave me a couple of spare ports for future expansion.

The Tormach PCNC440 arrived with US style push and lock black tubing and fittings with ubiquitous  1/4″ BSP threads.   Thank goodness something is common.   In total I had something like 15 threads to seal and PTFE tape did not do the job.   Soapy water revealed a bubble factory.

A quick scan on the web and it seemed that Loctite 577 was recommended.  RS had it in stock and it was a revelation to seal the threads.  You just squeeze a thin ring of 577 around the thread and screw it home.  Job done ….. but maybe they won’t ever come apart again …. well that’s a problem for another day.
