Stainless Steel Dairy Union End Caps Supplier in Saudi Arabia

Dairy Union End Caps

Our Hygienic Stainless Steel Union End Caps (also known as Blanking Caps or Blind Unions) are essential for the secure, aseptic termination of process lines. Designed to integrate perfectly with SMS 1146 and DIN 11851 union assemblies, these caps are manufactured from high-grade SS 304 and SS 316L. Featuring a mirror-polished internal face (Ra < 0.6μm), they provide a leak-proof, dead-leg-free seal for B2B applications in food, beverage, and pharmaceutical manufacturing.

Product Overview

A Hygienic Union End Cap is a specialized termination fitting used to seal off a male-threaded union part. Unlike a standard pipe cap, these are designed to be used in high-purity systems where regular dismantling for cleaning or system expansion is necessary. They provide a flush, hygienic seal that prevents product stagnation at the end of a header.

Aseptic Termination & Safety

In a hygienic process, any unused port must be sealed to maintain system pressure and sterility. Our union caps utilize a solid Blanking Disc (Liner) that sits against the male union part. When the nut is tightened, it compresses the gasket to create an airtight, metal-to-metal reinforced seal. The design ensures there are no crevices or “dead legs,” making it fully compatible with Clean-in-Place (CIP) protocols.

Precision Standards for Global Systems

We offer blanking solutions for the two most common international hygienic union standards:

  • SMS Standard: Featuring a flat-faced blanking disc, commonly used in beverage and liquid food manifolds.

  • DIN 11851 Standard: Featuring a heavy-duty blanking liner with a characteristic profile, widely used in European pharmaceutical and chemical process skids.

Superior Metallurgy and Surface Finish

Constructed from AISI 316L Stainless Steel, these caps offer maximum resistance to corrosion and chemical sanitizers. All wetted surfaces are mirror-polished to Ra < 0.6μm, ensuring the fitting remains free of bacterial harbor points and is easy to sterilize during Steam-in-Place (SIP) cycles.

Applications

  • Process Header Termination: Securely sealing the end of a main distribution header in beverage plants while allowing for future line extensions.

  • Manifold Branch Plugging: Terminating unused branch ports on multi-way hygienic manifolds to maintain system pressure during production.

  • Aseptic Tank Ports: Plugging unused inlets or outlets on stainless steel storage silos and fermentation vessels in the dairy and brewing industries.

  • Pharmaceutical Skids: Providing a sterile, removable cap for clean-water (WFI) and liquid medicine transfer lines during system maintenance.

  • CIP System Isolation: Using blanking caps to isolate specific sections of a process line during localized Clean-in-Place cycles.

  • Sampling Port Sealing: Providing a heavy-duty hygienic seal for sampling points when the sampling valve has been removed for sterilization.
