Why Choose Stainless Steel Fittings for Hydraulic Fittings? We recommend 304 and 316 quality Stainless steel fittings for most hydraulic applications. Stainless steel is a strong, durable metal with a high level of heat resistance. It also has the added benefit of chemical and corrosion resistance, which fits hydraulic applications and extends the service life of an application. Due to its high strength, strength, and corrosion resistance, stainless steel is typically more expensive than fittings made from other materials. However, investing in stainless steel fittings is significantly more beneficial than purchasing cheaper components that require costly maintenance and more regular replacement. Stainless steel has all the strength and durability of steel with a strong chemical and corrosion resistance suitable for hydraulic applications. This enhanced corrosion resistance extends the service life of the #pipeline. Stainless steel can withstand a variety of environments and a temperature range of -254 degrees Celsius to +649 degrees Celsius.
