ST Series Stainless Steel Straight-Through Couplings | Non-Valved Full-Bore Design for High Viscosity Fluids
ST Series Stainless Steel Straight-Through Couplings | Non-Valved Full-Bore Design for High Viscosity Fluids
The ST Series straight-through couplings deliver unrestricted fluid/gas flow with a smooth, full-bore design, ideal for viscous media like greases. Engineered without self-sealing valves, they eliminate flow restrictions and pressure drops, ensuring consistent performance in demanding industrial applications. Constructed in corrosion-resistant stainless steel, these couplings safely handle aggressive fluids, chemicals, and high-temperature environments. Their alternative hose stem connections enable compact, leak-free installations with minimal joints, reducing maintenance risks. Suitable for lubrication systems, chemical transfer, food processing, and heavy machinery, the ST Series guarantees reliability in high-viscosity applications where uninterrupted flow and durability are critical.
