Frequently Asked Questions

Check your sprayer or pump’s IPL/service manual. If the parts list explicitly shows 164920 in the packing stack, it is the correct replacement. If it’s not listed, do not substitute.

PTFE provides strong chemical resistance and low friction, which helps reduce wear, maintain pressure, and stabilize spray performance across a wide range of coatings and solvents.

Best practice is to inspect and service the entire packing stack together. Mixing worn and new elements can shorten service life. Follow the manufacturer’s service procedure for your model.
