Description
Straight Compression Unions
Compression unions for connecting tubing in centralized lubrication systems.
These straight compression unions are used to connect two lengths of tubing in-line, creating a secure, leak-resistant seal. Ideal for grease or viscous oil systems, they’re commonly used in centralized lubrication systems on construction equipment, industrial machinery, and commercial vehicles. Built to DIN 2353 and ISO 8434-1 standards, and available in LL and L pressure series.

Material & Benefits: Steel Zinc-nickel (CrVIF)
Our steel fittings feature a Zinc-nickel (CrVIF) alloy coating, electroplated directly onto the surface for superior corrosion resistance and durability. This finish combines approximately 10–15% nickel with zinc to form a hard, smooth, and long-lasting protective layer—making it an ideal alternative to traditional zinc or cadmium coatings.
Benefits of Zinc-nickel Coating
- Provides up to 10x more corrosion resistance than standard zinc
- Offers improved wear resistance for moving parts
- Withstands thermal stress better than conventional finishes
- Commonly used in automotive and aerospace applications
