Dow Corning #7 Release Compound is a high-quality silicone lubricant that is recommended for use on all rubber seals and o-rings used in water treatment equipment.  It is safe for use in potable water treatment applications, and will not harm rubber seals or molded plastic parts as petroleum-based lubricants can. 

This is the only lubricant recommended for use on CSI and Water Soft systems. Available in 150 gram (5.3 oz) tube, or one-time-use 1.5 gram tube.

Note: 1.5 gram tube comes automatically with every 20561X253 seal and spacer kit
