304 Stainless Hydraulic Sleeve

ISO 9001:2015, CE and RoHS compliant, the XYOON 304 Stainless Hydraulic Sleeve is a corrosion-resistant bite-type component for stainless steel tube connections. Made of genuine 18/8 stainless steel with a passivated surface, it delivers reliable metal-to-metal sealing at temperatures from -40°C to +200°C with 1000+ hours salt spray resistance. No plating peeling risk, RoHS compliant, ideal for food, beverage, water treatment, and semiconductor auxiliary piping. Material traceability with MTR certificate per batch.

Product Definition & Function

304 Stainless Hydraulic Sleeves are precision compression components for stainless steel seamless tube connections. When compressed axially, the sleeve edge bites into the tube wall to form a permanent, corrosion-resistant seal, replacing carbon steel sleeves in rust-prone and clean-media scenarios.

No plating peeling risk, no pollution to conveyed media

Resists atmospheric corrosion, fresh water and weak acid/alkali environments

Compatible with 304 seamless steel tubes and sanitary grade pipelines

Frequently Asked Questions (FAQ)

1、Will 304 stainless steel rust in coastal areas?

304 resists atmospheric and fresh water corrosion, but may develop surface rust in long-term high-salt coastal environments. We recommend 316 for coastal and seawater scenarios.

2、Can 304 Stainless Hydraulic Sleeves be used with stainless steel tubes of different hardness?

Yes, our edge angle is optimized for standard stainless steel seamless tubes to ensure reliable bite without cracking.

3: Can 304 stainless sleeves be used in high-temperature applications?

A: Yes, they operate stably from -40°C to +200°C, making them suitable for hot water, thermal oil, and high-temperature process lines.

4: What is the difference between 304 and 316 stainless steel sleeves?

A: 304 is suitable for atmospheric, fresh water, and mild chemical environments. 316 contains molybdenum, offering superior resistance to chlorides and seawater, recommended for coastal and marine applications.

5: Do you provide material test reports?

A: Yes, each batch comes with a complete MTR (Material Test Report) verifying chemical composition and mechanical properties, ensuring full material traceability.
