Bullard 88VX lens covers are sacrificial Mylar layers that protect the underlying viewing lens from abrasive rebound, overspray and debris. Replace the cover when visibility becomes reduced rather than treating it as the primary lens.
7714 is the clear rectangular adhesive-backed cover. 88VXLC is the clear oval perforated-edge cover with pull tab; B88VXLC is the bulk 10 × 25 version. MMB88VXLC is a clear 0.005 in. Mylar bulk sell unit supplied as 25 packs of 10.
Lens covers do not replace the required inner or outer lens. Match the cover style and window geometry to the existing 88VX setup.
