Sight Plugs
Sight plugs from Lube Devices, a part of LDI Industries, are ideal for quick visual inspection to detect presence of oil in gear cases / bearing housing and indicate liquid levels in reservoirs. These units feature clear glass for clarity and unobstructed visibility. Low-pressure models feature tamper-resistant construction, whereas high-pressure models have fused, one-piece construction allowing high operating temperatures & pressures. Raptor Supplies offers a broad range of Lube sight plugs for operating pressure ranging from 10 to 1750 psi.
