Installation and Maintenance

Installation

Inspect the Socket Fig 270A197 NPTbefore installation to ensure no sand holes, cracks, deformation and intact threads free of burrs
Clean pipe ends and internal threads of the Socket Fig 270A197 NPTto remove iron filings, dust and oil
Wind PTFE tape clockwise (4-6 layers) on male pipes or apply pipe thread sealant
After hand-tightening, use a pipe wrench to tighten evenly to avoid cracking due to excessive force
Conduct water/air pressure test at system rated pressure after installation; put into use only after confirming no leakage

Maintenance

Regularly check joints for leakage, thread looseness and surface corrosion
For outdoor or humid environments, reapply anti-rust paint annually for black-finish Socket Fig 270A197 NPTs and repair zinc layer promptly for galvanized ones
Replace immediately in case of cracks, severe corrosion or leakage after shutting down and relieving pressure
