Oil Level Indicators & Plugs

Oil Level Indicators & Plugs

Discover our extensive range of professional‑grade level indicators and screw plugs manufactured by Kipp — including oil‑sight glasses, fluid‑level indicators, vent screws, sealing plugs and threaded plugs for tanks, gearboxes, reservoirs and hydraulic systems.

How They Can Be Used:

Monitor Fluid or Oil Levels Visually: Use sight‑glass and level‑indicator elements to check oil, coolant or hydraulic fluid levels in tanks, gearboxes, reservoirs or hydraulic systems — allowing for quick, reliable visual inspections without opening the system.
Ensure Safe Sealing & Venting: Screw plugs and vent screws help seal openings securely to prevent leaks of liquids, gases or contaminants; vented options also allow pressure equalization where necessary.
Facilitate Maintenance & Refilling: With clear level indicators, you can easily monitor fluid levels and refill or change fluids before they fall below required thresholds — helping avoid damage or downtime.
Support Industrial & Mechanical Applications: Ideal for use in engines, gearboxes, hydraulic units, compressors, pumps, storage tanks and similar equipment to maintain proper fluid levels and system integrity.
Durable, High‑Quality Construction: Our level indicators use robust materials (e.g. polyamide, aluminium contrast screens, reliable sealing rings) designed for mechanical strength, pressure and fluid resistance — ensuring long-term reliability even under demanding conditions.
