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 ASME B31.3 (NPT) ratings from 3,900 to 11,000 psi; the table on this page gives the figure for each size. Treat them as the manufacturer's figures, not a guaranteed minimum.

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 28 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: Male Female Connector m NPT X f NPT, 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 NPT Male × NPT Female Adapter is a straight adapter in 316L stainless steel, forged from one piece. It carries an NPT male end and an NPT female 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 adapter
End 1: NPT male
End 2: NPT female
Material: 316L stainless steel, forged

Ends and sealing

NPT: taper pipe thread that seals on the thread flanks, with sealant or tape; ASME B1.20.1.

Sizes

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

End 1: 1/8" NPT (1/8-27) to 2" NPT (2-11.5)
End 2: 1/8" NPT (1/8-27) to 2" NPT (2-11.5)

Pressure rating

Manufacturer's published ratings (ASME B31.3 (NPT)), from 3,900 to 11,000 psi depending on size and end:

Size designator	NPT size	Male (psig)	Male (bar)	Female (psig)	Female (bar)
1	1/16	11000	757	6700	461
2	1/8	10000	689	6500	447
4	1/4	8000	551	6600	454
6	3/8	7800	537	5300	365
8	1/2	7700	530	4900	337
12	3/4	7300	502	4600	316
16	1	5300	365	4400	303
20	1 1/4	6000	413	5000	344
24	1 1/2	5000	344	4600	316
32	2	3900	268	3900	268

Parker equivalents

For 17 of the 28 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: Male Female Connector m NPT X f NPT.

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.
