Sioux Chief 963-01 Silicone Lubricant 0.25 Oz

Product Description

The SIOUX CHIEF 963-01 is a silicone-based lubricant packaged in a 0.25 oz tub, designed for use across a wide range of plumbing and mechanical applications. It remains stable and effective across an operating temperature range of -40 to 400 degrees F, making it suitable for both cold-weather and high-heat service conditions. This lubricant is commonly applied to rubber gaskets, O-rings, valve seats, and other sealing components to ease assembly and reduce wear. Plumbers and pipefitters rely on it as a standard shop-and-field consumable.

This silicone lubricant is well-suited for residential and commercial plumbing installations where rubber or elastomeric components require lubrication during assembly or maintenance. Typical applications include faucet cartridge installation, ball valve service, compression fittings, and O-ring seating. The compact 0.25 oz tub format is practical for service calls and tool bag storage. Because silicone lubricant is chemically inert and non-petroleum-based, it will not degrade rubber seals or plastics, making it appropriate for use on potable water system components where allowed by local code.

Key Features

• Wide service temperature range of -40 to 400 degrees F for hot and cold applications
• Silicone-based formula is safe for use on rubber, O-rings, and plastic components
• Compact 0.25 oz tub format for portability on service calls
• Non-petroleum base will not degrade elastomeric seals
• Suitable for plumbing, valve, and fitting assembly tasks

Compatibility

Designed as a general-purpose silicone lubricant for use with rubber gaskets, O-rings, valve seals, and elastomeric components in plumbing and mechanical assemblies.

Installation Notes

Apply a thin, even coat to the contact surface of the gasket or O-ring before assembly. Shut off water supply and depressurize the line before servicing any valve or fitting. Follow local plumbing codes regarding approved lubricants for potable water service. Avoid over-application, as excess lubricant can attract debris and compromise sealing surfaces.
