316 Stainless Single Ferrule Male Flare Connector, Tube × 37° JIC Male

The 316 Stainless Single Ferrule Male Flare Connector, Tube × 37° JIC Male is an instrumentation tube fitting in 316L stainless steel, forged. Its tube end uses a nut with a single ferrule that grips and seals on the outside of the tube; the manufacturer designs it to hold its seal through vibration, temperature swings and pressure cycling in instrument, sampling and control lines.

Construction

• Form: Male Flare Connector, Tube × 37° JIC Male
• Ferrule system: single ferrule
• End 1: tube end (nut and ferrule)
• End 2: 37° JIC male
• Material: 316L stainless steel, forged
• Bar stock: ASTM A479, ASTM A276

Ends and sealing

• Tube end: a nut with a single ferrule that grips and seals on the outside of the tube. Fit it to tube of the listed outside diameter; the pressure the joint holds depends on the tube wall.
• 37° JIC: 37° flare, a metal-to-metal seat on a 74° included cone; SAE J514 / ISO 8434-2.

Sizes

10 part numbers, 5/8" to 1/2" tube. The Sizes & Part Numbers tab lists the size on each end for every one.

• End 1: 5/8" tube to 1/2" tube
• End 2: 5/8" JIC 37° (7/8-14) to 1/2" JIC 37° (3/4-16)

Pressure rating

A tube fitting is rated to the tube it is made up on. The manufacturer publishes working pressures for 316 stainless tubing by outside diameter and wall thickness, from 2,000 psi to 12,000 psi (psi, by tube O.D. in inches and wall in inches):

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.
