Review on Secbolt Horizontal Air Compressor Pressure Switch Control Valve 90-120 PSI - Efficient Manifold Regulator Gauges by Andrew Agarwal

This was an inexpensive direct replacement for a faulty manifold/regulator on my 5hp compressor. I would give it 5 stars if it weren't for the difficulty of sealing all the joints. I followed the instructions and used the included thread sealant on all connections. But no matter how hard I tried, it wouldn't seal all the connections. Although the instructions specifically state not to use teflon tape on the threads for fear of breaking the cast manifold, this was my only option to seal the threads on the gauges as both gauges bottomed out before they were fully tightened. Otherwise it works as advertised. Gets the compressor up to the correct PSI and shuts down as expected. Generally satisfied except for leaks.
