Extreme-Pressure Stainless Steel Threaded Pipe Fittings
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. BSPP and metric male threads have either a gasket or a gasket and washer to prevent leaks.

Compact Extreme-Pressure Steel Threaded Pipe Fittings
These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces. They are galvanized and zinc-plated steel, which have better corrosion resistance than plain steel fittings. BSPP and metric male threads have either a gasket, or a gasket and washer, to prevent leaks.
