Product Introduction

YePV Connector Dust Protect Caps are professional EPDM protective covers for solar DC connectors. They effectively block dust, moisture and outdoor contaminants from unused or temporarily disconnected PV connectors during transportation, installation, commissioning and maintenance.

Dirty and oxidized connectors cause poor contact resistance, corrosion and solar system failure. YePV dust caps keep connector terminals clean, secure electrical stability and extend the service life of PV systems. Made of premium EPDM material, these caps feature strong elasticity, weather resistance and reliable sealing. Fully compatible with mainstream MC4 / PV4.0 solar connectors for residential, commercial and utility-scale solar projects.
