Hylomar Jointing Compound

The Rocol Hylomar Jointing Compound is a professional-grade non-setting sealant designed for demanding metal-to-metal and plastic-to-plastic sealing applications across automotive, industrial and engineering environments. This blue non-setting compound excels in applications where components are subjected to extreme vibration and distortion, making it particularly effective for sealing flanges in heavy-duty machinery and engine assemblies. The formulation remains pliable rather than curing hard, allowing joints to accommodate movement whilst maintaining an effective seal against pressures of up to 35 bar (500 psi). The non-setting nature of this jointing compound offers significant practical advantages for maintenance engineers and mechanics. Joints remain easy to break and clean when disassembly is required, eliminating the time-consuming removal work associated with traditional setting sealants. This characteristic makes it ideal for applications where regular servicing or inspection access is necessary. With an operating temperature range from -50°C to +250°C, this sealant maintains its sealing properties across the extreme temperature variations found in automotive engines, industrial pipework systems and high-performance machinery.

Features and Benefits:

• Non-setting formulation allows easy disassembly and cleaning of sealed joints
• Withstands pressures up to 35 bar (500 psi) for reliable sealing in demanding applications
• Operates across temperature range of -50°C to +250°C for versatile use
• Effective on metal-to-metal and most plastic-to-plastic joints
• Particularly suited to flanges subject to extreme vibration and distortion
