ASTM B 1029 : 2024

1.1This practice covers a procedure for making permanent press-connect joints by compressing an elastomeric sealing element between seamless copper and copper alloy tube and fittings.

1.2This procedure applies to press-connect fittings of pressurized systems such as plumbing, facility water, domestic water, vacuum, compressed air and gases, heating, ventilating and air conditioning, hydronic glycol, refrigeration, condenser and chilled water, and fire suppression sprinkler.

1.3This procedure does not apply to the assembly of electrical or electronic systems.

1.4Techniques for satisfactory joint preparation are referenced in ASME B31.5, ASME B31.9, and Practice B828.

1.5Tube and fittings are manufactured within defined tolerances to accommodate small variations in dimensions associated with manufacturing practice.

1.6A variety of elastomeric sealing element compounds are available. Select correct seal based on application and as recommended by the manufacturer.

1.7Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
