The press-connect system (tube, fitting, and joint) conforming to this Standard is for use at a maximum pressure of 1 380 kPa (200 psi) over the temperature range from 0°C to 93°C (32°F to 200°F).

This Standard provides requirements for fittings suitable for press-connect joining and covers the following:

(a) size designations

(b) pressure–temperature ratings

(c) terminology

(d) dimensions and tolerances

(e) materials

(f) design qualification

(g) required installation instructions

(h) markings
