Bioprocessing equipment (BPE) fittings are a special type of fitting used for high-purity end markets, such as biotech, pharmaceutical, cosmetic , personal care, and semiconductor that require strict cleanliness and production practices. Compared with sanitary fittings, BPE clamp and weld fittings are made to more stringent standards regarding dimension tolerances, interior surface finish (Ra), material traceability and packaging.
BPE Fittings
BPE compliant fittings are available in a variety of sizes up to 4”, based on the ASME BPE DT Tables. Steel & O’Brien is an active participant with ASME and has employees serving on various ASME BPE committees.
Steel & O’Brien carries a broad assortment of 316 stainless steel BPE clamp fittings and weld fittings in a variety of shapes, end connections, configurations, sizes and interior surface polish options that comply with ASTM BPE standards. We maintain a large inventory ready to ship. To prevent damage and contamination, all BPE sanitary fittings are capped and shipped in transparent bags.
Every BPE fitting is permanently marked for full traceability back to the original stainless steel used to make the part. Material Test Reports (MTRs) are included in each shipment and are also readily available online. A highly trained Steel & O’Brien staff member inspects each part, ensuring that it meets the latest ASME BPE fittings specifications.

FAQs
What are ASME-BPE fittings used for?
ASME-BPE fittings are used in pharmaceutical, biotech, and high-purity applications requiring enhanced cleanability, tighter tolerances, and full documentation.
What materials are used for BPE fittings?
BPE fittings are typically manufactured from 316L stainless steel with controlled sulfur content to support consistent orbital welding.
What surface finishes are available for BPE fittings?
Common finish options include SF1 (20Ra mechanical polish) and SF4 (15Ra electropolished).
Do BPE fittings include documentation?
Yes. BPE fittings are supplied with MTRs, surface finish certifications, and ASME-BPE compliance documentation.
Are Steel & O’Brien BPE fittings compatible with other BPE components?
Yes. They are compatible with other ASME-BPE-compliant components when finish and connection styles match.
