The ASTRWK EPDM Replacement Seal Kit is designed for users who require an alternative sealing material for specific spraying applications. Manufactured from durable EPDM material, this complete replacement seal kit is commonly used with acetone-based products, xylene-based products, and many solvent-based concrete sealers where EPDM-compatible seals are preferred. Replacing worn or damaged seals can help improve pressure retention, reduce leakage, and restore reliable sprayer performance. This seal kit is compatible with ASTRWK 1 Gallon, 1.5 Gallon, and 2 Gallon Stainless Steel Pump Sprayers.
