This Standard establishes requirements for cast copper alloy, wrought copper, and wrought copper alloy press-connect pressure fittings for use with hard-drawn seamless copper water tube conforming to ASTM B88 for piping systems conveying water. 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) terminology

(b) size designations

(c) marking

(d) material

(e) dimensions and tolerances

(f) required installation instructions

(g) pressure-temperature ratings

(h) design qualification
