Flange Ordering Information - Rectangular W/G

The table to the right shows ATM's numeral designation as it corresponds to flange type.

Flange types are noted as suffixes in the ATM model number system, ex.: the Suffix "-2" indicates that a CPRF Flange is the designated flange interface.

Note: Some flange types may not be available for a given W/G size.

Flange Ordering Information - Double Ridge W/G

The table to the right shows ATM's numeral designation as it corresponds to flange type.

Flange types are noted as suffixes in the ATM model number system, ex.: the Suffix "-G2" indicates that a Grooved, all tapped holes flange is the designated flange interface.

Note: Some flange types may not be available for a given W/G size.
