Product description
The Stainless Steel JIC 37° Bulkhead Locknut is a bulkhead locknut in 316L stainless steel, forged from one piece. It carries a 37° JIC 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: bulkhead locknut
- End 1: 37° JIC female swivel
- Material: 316L stainless steel, forged
Ends and sealing
- 37° JIC: 37° flare, a metal-to-metal seat on a 74° included cone; SAE J514 / ISO 8434-2.
Sizes
12 part numbers, 1/8" to 2". The Sizes & Part Numbers tab lists the size, dimensions in millimetres and the Parker equivalent for every one.
- End 1: 1/8" JIC 37° (5/16-24) to 2" JIC 37° (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 11 of the 12 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.
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.
