This heavy-duty tube coupling series addresses the critical requirements of systems operating at static pressures up to 200 PSI. The four-bolt configuration with galvanized steel construction distributes clamping force effectively across heavy-wall pipes, helping to prevent slippage and maintain pressure containment under operational stress. Our innovative eyelet design improves electrical conductivity, reducing static buildup risks in combustible dust environments.
Heavy-duty pipe coupling specifications include:
- Size range: 3.5-inch to 8.625-inch outer diameter tubing
- Pressure rating: Up to 200 PSI static pressure
- Gasket options: Abrasion-resistant SBR (black) or FDA-compliant NBR (white)
- Optional upgrades: T304 stainless steel construction, VMQ silicon gaskets for elevated temperatures, FPM Viton gaskets for caustic environments
- Installation features: Flanged nuts reduce assembly time, stainless steel gasket protectors available
