The components of this acid-resistant sprayer are unique. Standard sprayers have rubber O-rings, gaskets, and seals. The rubber disintegrates with harsh chemicals, and the trigger sprayer stops working. In contrast, this gold and black sprayer has Viton O-rings, gaskets, and seals. As a result, this revolutionary trigger sprayer does not leak, and it outperforms cheaper sprayers on the market, especially with acid-based and harsh chemicals.
