UltraPure Fittings

High-purity biopharmaceutical fittings you can rely on

  • Faster cleaning times thanks to high-quality, interior surface finishes
  • More uptime thanks to maximum cleanability and contaminant-free weld quality
  • Full traceability from raw material to the finished product
  • Highest quality guaranteed in accordance with ASME BPE standards
  • Global presence, solid support and service

Connecting high-purity processing lines calls for the highest levels of hygiene, safety, quality, and installation ease. Part of a broad portfolio of high-purity solutions, Alfa Laval Tri-Clover UltraPure fittings meet stringent requirements, such as the EN 10357-A and the ASME BPE standards, required to connect the piping systems of bioprocessing equipment. Easy to order, these BPE fittings provide maximum cleanability and are backed by a global organization and solid customer support.


How does UltraPure fittings work?


All Tri-Clover UltraPure tubes are manufactured according to stringent Alfa Laval specifications in our own factories to ensure the best possible levels of hygiene in ultra-clean processes. Manufactured to ensure dimensional accuracy and structural integrity, they are easy to install and have good corrosion-resistance for a long service life. Manufactured in compliance with ASME BPE.

Unions, clamp fittings and flanges

A wide range of flanges and clamp fittings enables you to find the most suitable for your process. All are designed for easy, rapid maintenance. Where the load on seals is extra high, and where you need effective cleaning, we recommend flanges and clamps with finger nuts for ease of inspection and, if required, ease of replacement. Seals are available in nitrile rubber (NBR), fluorine rubber (FKM/FPM) and ethylene propylene (EPDM). Unions are compliant with standards including ISO, DIN and ASME.


To provide maximum structural integrity and trouble-free flow, Alfa Laval manufacturing processes focus on tight tolerances and uniform wall thicknesses to maintain exact angles and uniform in all connections.


Connections between tubes or pipes with different sizes or shapes are often a prime location for leakage in a flow stream. Alfa Laval reducers feature cylindrical welding ends and uniform wall thicknesses for all tube combinations which ensures the right diameter and wall thickness for each specific flow stream and helps eliminate the risk of leakage.

Tee junctions

Alfa Laval tee junctions have uniform wall thickness, tight tolerances, and a wide selection of finishes to ensure high strength and long service life, and problem-free welding and assembly. All tees are made of AISI 316L stainless steel and are available in 1”- 4” diameters.

Material and mill test certifications

All Alfa Laval UltraPure tubes and fittings are supplied with a certificate verifying compliance both with the specifications according to 3.1 Material Certification and with Mill Test Report (MTR) requirements certifying the chemical and physical properties of the materials.
