Thread Sealing Compound for Hydraulic Systems SKU: QT0666690112

Hydraulic leaks start small—a tiny weep around threaded fittings that becomes a steady drip, then a costly stream that wastes expensive hydraulic fluid and creates safety hazards. This specialized jointing compound creates reliable, leak-proof seals on hydraulic pipe threads, preventing the contamination and fluid loss that can sideline equipment when you need it most.

Why Professional Compound Matters

• Designed specifically for hydraulic system pressures and temperatures
• Won't contaminate hydraulic fluid like tape that can shred and cause system damage
• Creates permanent seal that handles pressure cycling and vibration
• Compatible with hydraulic fluids and won't degrade over time

This compound is essential for sealing NPT, BSP, and other pipe thread connections on hydraulic pumps, valves, cylinders, and manifolds. Apply to clean threads before assembly for professional results that prevent comebacks.
