Description
Overview:
The Brown, Fine Threaded Hydraulic Pipe Sealant - 50 ml from Lockfast is a genuine, oil‐resistant thread sealing compound designed for fine-thread hydraulic and pneumatic fittings in plant, agricultural, and garden machinery. It helps prevent leaks by filling gaps between metal threads and curing in the absence of air, creating a reliable, pressure‐tight seal that resists vibration and fluid exposure. With medium viscosity for controlled flow into tight threads, it suits maintenance on equipment such as excavators and ride‐on mowers. Operating from -54°C to 150°C, it performs across cold starts and hot running conditions. Supplied in a 50 ml bottle for workshop use. Replaces Loctite 542. GTIN: 5060954881556. Genuine Lockfast part.
