Product description
The Stainless Steel NPT Female × JIC 37° Male Bulkhead Connector is a bulkhead connector in 316L stainless steel, forged from one piece. It carries an NPT female end and a 37° JIC 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: bulkhead connector
- End 1: NPT female
- End 2: 37° JIC male
- 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.
- 37° JIC: 37° flare, a metal-to-metal seat on a 74° included cone; SAE J514 / ISO 8434-2.
Sizes
13 part numbers, 1/8" to 1-1/2". 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" NPT (1/8-27) to 1-1/2" NPT (1-1/2-11.5)
- End 2: 1/4" JIC 37° (1/4-18) to 1-1/2" JIC 37° (1-1/2-11-1/2)

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 10 of the 13 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 NPTF Female × JIC 37° Male Bulkhead 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 the material, and Indus engineering will confirm the part number. Price and lead time are confirmed with the quotation.
