With the strength to handle extreme pressures, these fittings can be used to connect equipment in hydraulic fluid lines. 316 stainless steel fittings have excellent corrosion resistance.
NPTF (Dryseal) threads are compatible with NPT threads. BSPP and metric male threads have either a gasket or a gasket and washer to prevent leaks.

Made to tighter tolerances than other stainless steel pipe fittings, these are also known as instrumentation fittings. The male threads are rolled for extra strength in extremepressure applications. Fittings are commonly used to connect equipment in gas and hydraulic fluid lines. They are 316 stainless steel for excellent corrosion resistance.

Use these fittings in a lowpressure pipe line.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
Plugs with copper washer form a tight seal to prevent leaks. Also known as a crush washer, the washer compresses and deforms to fill gaps when tightened. Because it loses its shape when compressed, it’s not reusable. Made of copper, the washer resists rust. These plugs meet either DIN 908 or DIN 910, international standards for pipe plug dimensions.
Plugs with magnet attract metal debris that could otherwise damage your system.
NPTF (Dryseal) threads and NPSL (National Pipe Straight Locknut) threads are compatible with NPT threads.
