UMETA Grease Nipples are offered in different types including hyraulic, ball, flush, bayonet, and button-head. Standard versions made of bright and passivated zinc-plated steel, stainless steel (V2A + V4A), or brass according to international product standards (e. g. DIN, ISO, SAE, BS, JIS). They are case-hardened according to DIN, zinc-plated and passivated. They are essential for maintenance and repairs and can be used for protection of the lubrication point against dirt and humidity and standardized connection to the grease gun. Different applications of UMETA grease nipples include bearings, hinges for machines, vehicles, industry, cardan and drive shafts, linear guides, hydraulic cylinders, drives, chains, axes and others. 

UMETA hydraulic grease nipples have a conical thread, the head diameter is 6.5 - 0.2 mm. Upon request, UMETA can manufacture grease nipples with different measurements, threads, thread types (for example, cylindrical thread), with other opening pressures.

Hydraulic connectors 515/G - 516/G are recommended as nozzles with  the use of plastic caps for protection and conservation.

Mostly sold in packs of 100 pieces per pack or other number as specified after the letters "PK" in the product reference number (SKU).

A wide range of grease fittings (aka zerk fittings or grease nipples) are offered as part of our own labelled (AVIATIONEU NEW ERA) product lines. Sourced from quality manufacturers, they are competitively priced and can be furnished in different head types  (conical, button or flush head, drive-in or self-forming), straight or angled heads (30°, 45°, 65°, 67.5°, 90°) and thread sizes in metric or inch systems, depending on the selected fitting. Fittings are sold in pieces but mostly in packs a with specified number of fittings indicated after the letters "PK" in the product reference number (SKU). Fitting kits are also available with assortments of different fittings.

Hydraulic  & pneumatic fittings (also called compressed air connectors)  are used today in a wide range of applications as a connection for conductors such as hoses, tubes, pipes and machinery carrying fluids or gas and compressed air respectively to maintain their pressure without leakage. Whether their intended use is for fluids (hydraulic) or gas/compressed air (pneumatic) they are manufactured in a range of materials from plastic and aluminum to steel and stainless steel for maximum corrosion and chemical resistance. They come in different specifications (for military,aerospace or industrial uses), different thread types, such as British Standard Pipe (BSP) or U.S. National Pipe Thread (NPT/PTF) and sizes in inch or metric systems. Depending on the specific conductor/fitting application requirement different fittings are selected. Push-in fittings are quick and easy to install, connect and disconnect, even multiple times. Compressed air couplings,consisting of a socket and plug combination are self-sealing connecting components traditionally used for pneumatic tools, hall installations and laboratory equipment.  Compressed air distributors are the ideal choice whenever distribution of compressed air to different systems is required. Different types can be used to direct the compressed air from one access point to several  outputs at the required location.

Hydraulic  & pneumatic fittings are offered as OEM parts from well known manufacturers or as part of our own labelled (AVIATIONEU NEW ERA) product lines. They are included in different product presentations throughout our Web Platform. In addition, a comprehensive range of tools and accessories (separately presented) are also offered ranging from connecting and disconnecting pliers, tubing and pipe cutters to union nuts, sealing caps, hollow bolts, hose clips, tubing straps and others.

Extending our range of offered fittings for hydraulic systems and fluid power applications, JIC (Joint Industry Council) 37° flare fittings can be supplied as part of AVIATIONEU NEW ERA product porffolio. JIC fittings share the same 37° flare angle as AN (Army-Navy) fittings, listed separately but they exhibit significant differences in materials, design tolerances, and intended applications. Typically made from carbon steel, stainless steel, or brass, JIC 37° flare fittings are commonly used in agricultural equipment, construction, and general hydraulic industrial applications unlike AN fittings which were originally designed, developed and still widely used for military and aerospace applications meeting their strict performance requirements. Although JIC fittings are often interchangeable with AN fittings and also a cost-effective alternative for less demanding applications, AN fittings should be a prefered choice for aerospace,  military or critical applications in high-pressure or high-precision environments.
