What is it made from?

Forged carbon steel, trivalent zinc plated. The manufacturer states the material for 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.

37° JIC: 37° flare, a metal-to-metal seat on a 74° included cone; NPTF (Dryseal): Dryseal taper pipe thread, cut so the crests and roots close up as the joint is tightened, so it seals on the thread.

Can I match a Parker part number?

Yes, for 28 of the 33 sizes. The size table shows the Parker part number the manufacturer cross-references next to the Indus part number.

Is there a stainless-steel version?

Yes: Stainless Steel JIC 37° Male × NPT Female Connector 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 Steel JIC 37° Male × NPTF Female Connector is a straight connector, in forged carbon steel, trivalent zinc plated. Its ends are 37° JIC male and NPTF (Dryseal) female. The 37° JIC flare is the most widely used inch-size hydraulic connection on mobile and industrial machinery.

Construction

Body: straight connector
End 1: 37° JIC male
End 2: NPTF (Dryseal) female
Material: forged carbon steel, trivalent zinc plated

Ends and sealing

37° JIC: 37° flare, a metal-to-metal seat on a 74° included cone; SAE J514 / ISO 8434-2.
NPTF (Dryseal): Dryseal taper pipe thread, cut so the crests and roots close up as the joint is tightened, so it seals on the thread; ASME B1.20.3.

Sizes

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

End 1: 37° JIC, 1/8" to 2" (5/16-24 to 2-1/2-12)
End 2: NPTF (Dryseal), 1/8" to 2" (1/8-27 to 2-11.5)

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 28 of the 33 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.

Stainless-steel version

The same configuration in 316 stainless steel: Stainless Steel JIC 37° Male × NPT Female Connector.

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 Indus engineering will confirm the part number. Price and lead time are confirmed with the quotation.
