GT-L1 Series – High-Pressure Screw Connect Couplers (Holmbury SP Interchange)
Description:
The GT-L1 Series Screw Connect Hydraulic Couplers are designed for high-pressure applications, providing superior sealing, vibration resistance, and secure connections. Built to interchange with Holmbury SP Series, these couplers feature a screw-to-connect locking system, ensuring zero fluid leakage and excellent resistance to pressure spikes.
Manufactured from hardened steel with corrosion-resistant coatings, the GT-L1 Series is suitable for heavy-duty hydraulic applications, including construction equipment, mining machinery, high-pressure rescue tools, and industrial hydraulic systems. The couplers can be connected under residual pressure, making them perfect for demanding environments.
Key Features:
✅ High-Pressure Capability – Designed for applications up to 10,000 PSI
✅ Screw-to-Connect Mechanism – Prevents accidental disconnection under pressure
✅ Leak-Free Sealing – Ensures maximum reliability in harsh conditions
✅ Heavy-Duty Construction – Hardened steel body with corrosion-resistant plating
✅ Connect Under Residual Pressure – Enhances operational efficiency in hydraulic systems
✅ High Resistance to Vibration & Pressure Spikes – Ideal for extreme conditions
✅ Interchangeable with Holmbury SP Series – Seamless compatibility with existing systems
