Metric threads are standard terminating threads. They conform to IEC423 and BS6053. PG threads conform to the German DIN40430. NPT threads are American tapered threads. The taper is designed to seal on the thread itself and not on the face of the fitting. Outside diameter shown is maximum.

IP Rating Chart

This displays the full IP rating chart and definitions for protection against solids and liquids.

Protection Against Solids   Protection Against Liquids
1st Digit   2nd Digit  
0 No protection 0 No protection
1 Protection against solid bodies larger than 50mm 1 Protection against vertically falling drops of water (condensation)
2 Protection against solid bodies larger than 12mm 2 Protection against drops of water falling at up to 15 degrees from the vertical
3 Protection against solid bodies larger than 2.5mm 3 Protection against drops of water at up to 60 degrees from the vertical
4 Protection against solid bodies larger than 1mm 4 Protection against splashing of water from all directions
5 Protection against dust (no harmful deposits) 5 Protection against jets of water from all directions
6 Complete protection against dust 6 Protection against jets of water of similar force to heavy seas
    7 Protection against ingress of water to a depth of 1 metre
    8 No ingress when submerged at specified depth exceeding 1m for an unspecified time
