30° Flared Fittings for Steel Tubing
- For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Hydraulic Fluid, Mineral Oil, Water
- Specifications Met: See table
- Tubing: Use with steel
Also known as JIS (Japanese Industrial Standard) fittings, these have a 30° flare on one or both ends. Fittings are zinc-plated steel for fair corrosion resistance.
UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. They are also known as O-ring boss threads.

Low-Pressure Steel Unthreaded Pipe Flanges
Bolt two flat-surface flanges or two raised-surface flanges of the same size together with a gasket (sold separately) to create an access point in a pipe line. Flanges are for use with low-pressure applications in noncorrosive environments.
Butt-weld flanges are also known as weld-neck flanges. The flange neck has a beveled end that, when flush to pipe, creates a trough for a strong weld.
Slip-on weld flanges have no internal stop. Slide a pipe through the flange and weld on both sides.
Cap flanges are also known as blind flanges.
