FAQ
Q1: How do I choose the correct tank cap for my sprayer?
A: Measure the outer diameter of your tank neck threads (or inner diameter if female thread) and the thread pitch. Most sprayer caps use coarse thread (2–3mm pitch). Match these measurements to the cap specification.
Q2: What is the difference between NBR, silicone, and EPDM gaskets?
A: NBR (nitrile) resists oils and fuels. Silicone handles higher temperatures. EPDM provides excellent resistance to water, herbicides, and pesticides - recommended for agricultural sprayers.
Q3: Can I use this cap on any sprayer tank?
A: Not all sprayer tanks use the same thread size and pitch. Always verify your tank neck thread dimensions before ordering. Universal fit caps may not seal properly on non-standard threads.
