Product Overview: 316L Stainless Steel Push to Connect Fittings
Key Features
Material Excellence:
Body: Made from SUS316L stainless steel, offering superior corrosion resistance, especially in harsh environments.
Seal Rings: Constructed from FKM (Fluoroelastomer), ensuring excellent chemical resistance, high-temperature tolerance (up to +140°C), and long-term durability.
Compliance & Safety:
Complies with the Food Hygiene Law of the People’s Republic of China, making these fittings suitable for sanitary applications like food and pharmaceutical industries.
Quick-Connect Design:
Facilitates fast installation and disassembly without specialized tools, reducing downtime in maintenance and system reconfiguration.
High-Pressure Performance:
Operating pressure: 0–1.5 MPa (proof pressure: 1.8 MPa).
Certain high-pressure models (e.g., SSB-G) withstand up to 400 bar, ideal for demanding pneumatic systems.
Versatile Connection Types:
Threaded (male/female), ferrule, flange, and push-in designs to suit diverse piping requirements.
Temperature Range:
Stable performance in ambient and fluid temperatures from -20°C to +140°C.
Product Recommendations by Application
1. High-Pressure Pneumatic Systems
Recommended Model: SSB-G Series
Features: Male threaded tee-shaped fittings with G-thread connections (G1/8″ to G1/2″). Engineered for pressures exceeding 10 bar, these fittings are ideal for compressed air systems in manufacturing and automation.
2. Compact or Space-Constrained Installations
Recommended Model: SSL-G Series
Features: L-shaped male threaded elbows with G-threads, enabling efficient routing in tight spaces without compromising flow efficiency.
3. Flow Control Applications
Recommended Model: SS-SC Series
Features: Male threaded speed control throttle valves for precise regulation of fluid flow and pressure in hydraulic/pneumatic systems.
4. General-Purpose Straight Connections
Recommended Model: SSC Series
Features: Straight-through push to connect fittings with male threads (M5 to R1/2″), suitable for universal tubing systems.
5. Sanitary or Food-Grade Environments
Recommended Model: SSGJ Series
Features: Push-in straight-through fittings with 316L stainless steel construction, meeting hygiene standards for food and beverage processing.
Product Comparison: Key Differences
| Model Series | Primary Use | Connection Type | Pressure Rating | Unique Benefit |
| SSB-G | High-pressure systems | G-thread male | Up to 400 bar | Robust sealing for extreme conditions |
| SSL-G | Compact installations | G-thread male (L-shape) | 1.5 MPa | Space-saving 90° elbow design |
| SS-SC | Flow control | Male threaded | 1.5 MPa | Adjustable aperture for precision |
| SSCF | Female-threaded systems | G-thread female | 1.5 MPa | Compatibility with female ports |
| SSGJ | Hygienic applications | Push-in straight-through | 1.5 MPa | Tool-free installation |
Buying Guide: How to Choose the Right Fitting
Determine Operating Conditions:
Pressure: Select high-pressure models (e.g., SSB-G) for compressed air systems.
Temperature: Ensure the fitting’s range (-20°C to +140°C) matches your environment.
Identify Connection Requirements:
Thread type (male/female), size (e.g., G1/8″, R1/2″), and shape (straight, elbow, tee).
Material Compatibility:
Verify chemical resistance if handling aggressive fluids (e.g., acids, steam).
Industry Standards:
For food/pharmaceutical use, prioritize fittings compliant with hygiene laws.
Budget vs. Longevity:
316L stainless steel fittings offer higher upfront costs but reduce replacement frequency due to corrosion resistance.
