316 Stainless Hydraulic Sleeve

The XYOON 316 Stainless Hydraulic Sleeve is a high-performance bite-type component engineered for severe corrosive environments. Featuring genuine 316 alloy with molybdenum (16Cr-10Ni-2Mo), it delivers superior chloride and acid resistance with 2000+ hours salt spray protection. Operating from -40°C to +220°C, it is ideal for offshore, chemical, pharmaceutical and desalination applications. Electropolished surface (Ra≤0.8μm) available for pharmaceutical and high-purity systems. 100% material traceability with MTR certificate per batch.

Product Definition & Function

316 Stainless Hydraulic Sleeves are high-end compression components for severe corrosion environments. The 316 alloy with molybdenum delivers far better chloride and acid-base resistance than 304, forming permanent, reliable seals on stainless steel tubes in harsh working conditions.

Resists seawater, brine, weak acid and organic solvent corrosion

Excellent intergranular corrosion resistance, suitable for welding surrounding environments

Ideal for offshore, chemical, pharmaceutical and desalination projects

Frequently Asked Questions (FAQ)

1.What is the main difference between 316 and 304 hydraulic sleeves?

316 adds molybdenum element, which greatly improves chloride and acid corrosion resistance. It is suitable for seawater and chemical scenarios, while 304 is only for general atmospheric and fresh water environments.

2.Can 316 Stainless Hydraulic Sleeves be immersed in seawater for a long time?

Yes, 316 resists seawater corrosion well and is suitable for long-term immersion in seawater and brine environments.

3.Do you provide electropolished 316 sleeves for pharmaceutical use?

Yes, we provide electropolished surface with Ra≤0.8μm, meeting pharmaceutical high-cleanliness requirements.

4.Can you provide third-party material testing reports?

Yes, we can arrange SGS or other third-party material testing according to customer requirements.
