Steel & O’Brien has been manufacturing sanitary stainless steel fittings and process equipment since 1990. They carry 10,000+ catalog items and can fabricate custom parts when standard configurations don’t fit the application. Every BEECO build that needs reliable, traceable sanitary fittings starts with Steel & O’Brien.

Sanitary Fittings

S&O stocks 304 and 316L stainless steel sanitary fittings from 1/2” through 12” — over 10,000 SKUs on hand, ready to ship same day. The lineup covers every connection type used in hygienic process systems:

Fitting Type	Typical Use
Clamp (Tri-Clamp) & Ferrules	Quick-disconnect connections; standard for CIP-intensive systems
Butt Weld Fittings	Permanent, flush connections; elbows, tees, reducers, caps
Bevel Seat Fittings	Legacy dairy and food systems requiring self-draining connections
I-Line / Q-Line Fittings	Tubing runs in food, beverage, and dairy; resists pullout under pressure
BPE Fittings	Pharmaceutical and biotech; zero dead-leg, full drainability required
TI-Line / John Perry	Regional and legacy system compatibility
European / DIN Fittings	Imported equipment integration; DIN 11851 thread connections
Adapters, Caps, Clamps & Gaskets	System completion hardware; gaskets available in multiple elastomers

How to Choose the Right Sanitary Fitting

Selecting the right fitting comes down to three application-specific factors.

Factor	What to Consider	BEECO Application
Material Grade	304 for general food & beverage; 316L adds molybdenum for chloride and aggressive CIP resistance	BEECO specs grade based on process chemistry — not default to lowest cost
Surface Finish (Ra)	32 Ra for most food/beverage; 20 Ra for pharma; 15 Ra for high-purity. Lower Ra = fewer bacterial harborage points	S&O provides documented finishes down to 15 Ra, electropolishing and passivation available
Connection Type	Tri-clamp for frequent disassembly; butt weld for permanent flush runs; BPE where zero dead-leg is required	Connection type follows the process — CIP access, cleanability, and drainability all drive the decision

Heat Numbers & Material Traceability

A heat number is a unique identifier stamped on every fitting that links the finished part back to the specific melt batch of stainless steel it was produced from. That link is the foundation of material traceability.

When steel is produced at the mill, it is assayed and the results are recorded in a Material Test Report (MTR) — also called a Certified Mill Test Report (CMTR) or Mill Certification. The MTR documents the actual measured chemical and physical properties of that heat: carbon, sulfur, chromium, nickel, and other alloying elements. Once the steel is processed into fittings, the heat number follows the part through manufacturing and is stamped on the finished product. If questions ever arise about a fitting’s alloy, performance, or regulatory compliance, the heat number provides a direct path back to documented source data.

Every Steel & O’Brien fitting ships with its MTR. For BPE fittings, MTRs are included in each shipment and are also available online. Every BPE fitting is permanently marked for full traceability back to the original stainless steel used to make the part.

Why Heat Numbers Matter	What It Means for a BEECO Build
Proves the alloy is what it claims to be — 316L, not 304 mislabeled	BEECO can verify material grade before a fitting enters the system
Supports compliance with 3-A, ASME BPE, and FDA regulatory audits	Documentation is ready if a customer or inspector asks for it
Enables full recall traceability if a fitting fails in service	Root cause can be isolated to a specific heat — not the entire system
Confirms material can withstand CIP chemistry, autoclaving, and process temps	Eliminates guesswork on material compatibility in aggressive service environments

Why BEECO Specs S&O Fittings

Every BEECO system is built around what the product actually demands. That means the grade of stainless, the fitting type, the connection standard, and the documentation all follow from the process — not from what’s easiest to source.

• Inventory depth. 10,000+ SKUs on hand means BEECO isn’t waiting on fittings to close out a build.
• Custom capability. When a BEECO design calls for a non-catalog configuration, S&O produces it to drawing within days.
• Full traceability. S&O provides MTRs and heat numbers on all fittings — BEECO can verify alloy grade before a single fitting goes into a system. No guesswork on material compliance.
• Regulatory readiness. 3-A, ASME BPE, and ISO documentation travels with every order — a direct advantage when BEECO builds go into audited food, dairy, or pharmaceutical facilities.

That combination of range, speed, and documentation quality is why Steel & O’Brien is a standard supplier on BEECO builds across food, dairy, beverage, and pharmaceutical applications.
