What is it made from?

316L stainless steel, forged. The manufacturer states the material on every part in this family.

What pressure is it rated to?

The manufacturer publishes SAE J514 ratings from 1,000 to 5,000 psi; the table on this page gives the figure for each size. Treat them as the manufacturer's figures, not a guaranteed minimum.

SAE O-ring boss (ORB): SAE straight-thread port sealed by an O-ring under the hex; NPT: taper pipe thread that seals on the thread flanks, with sealant or tape.

Can I match a Parker part number?

Yes, for 17 of the 21 sizes. The size table shows the Parker part number the manufacturer cross-references next to the Indus part number.

Is there a carbon-steel version?

Yes: Steel ORB Male × NPTF Male Adapter, in zinc-plated carbon steel, is listed separately.

What is the lead time?

Price and lead time are confirmed with the quotation. Tell us if the job is urgent and we will say so before you order.

Product description

The Stainless Steel ORB Male × NPT Male Connector is a straight connector in 316L stainless steel, forged from one piece. It carries an SAE O-ring boss (ORB) male end and an NPT male end. 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 connector
End 1: SAE O-ring boss (ORB) male
End 2: NPT male
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.
NPT: taper pipe thread that seals on the thread flanks, with sealant or tape; ASME B1.20.1.

Sizes

21 part numbers, 1/8" to 2-1/2". The Sizes & Part Numbers tab lists the size on each end, dimensions in millimetres and the Parker equivalent for every one.

End 1: 1/8" ORB (5/16-24) to 2-1/2" ORB
End 2: 1/4" NPT (1/4-18) to 2-1/2" NPT (2-1/2-8)

Pressure rating

Manufacturer's published ratings (SAE J514), from 1,000 to 5,000 psi depending on size and end:

32	2	2 1/2-12	2	1500	1000

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 17 of the 21 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 Male × NPTF Male Adapter.

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.
