RPB® Nova 3® Inner Gasket

Part Number: NV3-721
Weight: 0.20 lbs

The RPB® Nova 3® Inner Gasket is an essential OEM replacement component designed to seal and secure the inner lens within the Nova 3® respirator’s multi-layer lens system. This gasket ensures a tight, reliable seal between the inner lens and the visor frame—preventing dust, debris, and abrasive media from infiltrating the helmet’s interior.

With constant exposure to high-impact environments and frequent lens changes, inner gaskets can wear out or lose elasticity over time. Replacing the gasket restores full sealing integrity, maintains operator safety, and preserves ANSI-rated lens protection.
