Description
Overview:
Loctite SI 5660 Gasket Grey Silicone - 100 ml is a genuine Loctite silicone sealant for replacing cut gaskets on machinery. The grey, durable silicone forms a flexible, form-in-place seal on flanges and covers, helping to prevent leaks where water or glycol are present. It is suitable for a wide range of construction and garden equipment, including engines, pumps, compressors, and gearbox housings. Operating from -55 to +200°C, it maintains sealing performance across cold starts and high running temperatures. The 100 ml tube allows accurate application along narrow or complex flange profiles. Resistant to fluids and minor vibration, it is a practical choice for workshop repairs and maintenance where reliability and ease of use are important. No hazard symbols or risk phrases are indicated.

Typical Applications:
Sealing flanged joints on engines, pumps, compressors, gearboxes, and machinery housings.

Suitable for maintenance tasks where a durable, flexible, and fluid-resistant seal is needed without cutting a traditional gasket.
