Metric O-ring set 

Metric O-rings designed for power hydraulics 

The following category includes all types of O-ring sets in convenient boxes ( boxes ) i.e. sorters. The most popular set is the Metric O-ring set BOX 419 pcs. , which contains 32 sizes of individual O-rings intended for broadly defined power hydraulics. O-rings of this type are resistant to, among others, engine, transformer, and heating oils, lubricants, hydraulic fluids, aliphatic hydrocarbons such as:propane, butane, gasoline, alcohols, oil-water emulsions of type HSA, HSB polyglycol-water mixtures of type HSC aqueous salt solutions, diluted acids and bases at low temperatures, water up to 60°C.

What are metric O-ring sets ?

Metric O-ring sets are sets of seals with circular cross-sections, made of durable and flexible materials such as NBR, FKM (Viton) or EPDM. They are intended for a variety of applications, both in power hydraulics and in other systems requiring tightness. Offered in practical organizers, they allow easy access to various O-ring sizes, making them an indispensable piece of equipment for every workshop or industrial plant.

Application of NBR metric O-rings

NBR O-rings are among the most popular O-rings used in broadly understood power hydraulics. Metric O-rings are used, among others, to seal conical connections on hydraulic hose fittings ( DKOL version with O-ring, DKOS versions with O-ring ) and are widely used in all types of metric thread nut fittings ( fittings with a swivel nut ). O-ring sets are used in many industries and technical systems: Power hydraulics: Tightness in hydraulic joints and actuators. Automotive: Sealing pumps, valves or fuel lines. Machine industry: Protection against leaks in lubrication and cooling systems. Equipment maintenance: Used in service centers for quick repairs of various types of devices and installations.
