Critical Electrical Protection:

Superlok® Dielectric Fittings match Swagelok’s® quality in insulating subsystems from electrical currents, voltages, and static charges, while offering better value. Our fittings are specifically engineered for natural gas pipelines and monitoring stations, providing the same protection at a more competitive price point.

Superior Material Selection:

Like Swagelok®, we use premium materials but with better availability:

• 316 Stainless Steel for strength and corrosion resistance
• PEEK insulator for excellent thermal and chemical resistance
• 70 Durometer VITON O-rings for superior sealing
• Virgin PTFE back-up washers for low friction

Exceptional Performance Specifications:

Matching Swagelok’s® standards while offering better value:

• Electrical Resistance: 10 X 10⁶ Ω at 10V (dc) at 70°F
• Pressure Rating: Up to 5000 psig (344 bar)
• Temperature Range: -40 to 200°F (-40 to 93°C)

Versatile Connection Options:

Our fittings provide the same connection versatility as Swagelok®, including gaugeable tube fittings and tapered pipe thread end connections, while offering:

• More competitive pricing
• Better availability
• Faster delivery times
• Complete interchangeability

Enhanced Thermoplastic Insulation:

Superior electrical, chemical, and UV resistance with better water absorption properties than Swagelok®, ensuring long-term dielectric strength across diverse operating conditions.
