Product description
The Stainless Steel ORB Female Coupling is a straight coupling in 316L stainless steel, forged from one piece. It carries two SAE O-ring boss (ORB) female ends. Stainless steel is chosen where corrosion rules out zinc-plated carbon steel: offshore and marine lines, chemical, fertiliser and petroleum plant, and food, beverage and pharmaceutical process equipment.
Construction
- Body: straight coupling
- End 1: SAE O-ring boss (ORB) female
- End 2: SAE O-ring boss (ORB) female
- Material: 316L stainless steel, forged
Ends and sealing
- SAE O-ring boss (ORB): SAE straight-thread port sealed by an O-ring under the hex; SAE J1926 / ISO 11926.
Sizes
9 part numbers, 1/4" to 2". The Sizes & Part Numbers tab lists the size on each end and the Parker equivalent for every one.
- End 1: 1/4" ORB (7/16-20) to 2" ORB (2-1/2-12)
- End 2: 1/4" ORB (7/16-20) to 2" ORB (2-1/2-12)

NOTE: Since many factors influence the pressure at which a system will or will not perform satisfactory, values shown in this table should not be construed as guaranteed minimum.
Parker equivalents
For 7 of the 9 sizes the size table gives the Parker part number the manufacturer cross-references, so a part number taken off existing equipment can be matched to the Indus part number.
Carbon-steel version
The same configuration in zinc-plated carbon steel: Steel ORB Female Coupling.
How to order
Quote the Indus part number from the size table. If you only have the fitting, send the thread or tube size on each end and the material, and Indus engineering will confirm the part number. Price and lead time are confirmed with the quotation.
