Semiconductor & High-Purity Applications
CFOS & High-Purity Semiconductor Flow Control Materials
Smithco Industrial Supply provides CFOS, high-purity and ultra-high-purity stainless steel tube, pipe, fittings and flow-control materials for semiconductor fabs and other controlled-process applications. We support project requirements for bulk and specialty gas distribution, clean-process piping and instrumentation with specification-driven sourcing, documentation and coordinated delivery.
Our sourcing capabilities include recognized semiconductor-industry manufacturers such as Valex and Dockweiler, along with qualified alternate manufacturers when approved by the project specification. Smithco works with customers to address availability, lead times, material traceability, cleanliness, finish and documentation requirements across complete material packages.
CFOS & High-Purity Stainless Steel
CFOS tube, pipe & fittings for clean-process systems
Smithco supplies CFOS (Clean For Oxygen Service) and high-purity stainless steel tube, pipe, fittings and flow-control components for semiconductor fabs, clean-process systems, bulk and specialty gas distribution, and other demanding high-purity applications. Product options can include 304/304L and 316/316L stainless steel, bright-annealed and electropolished finishes, controlled-cleanliness processing, traceability, clean packaging and project-specific testing or documentation requirements.
High-purity stainless steel fittings with full material marking and heat traceability.
Product scope
- CFOS stainless steel tubing, tube and pipe
- CFOS weld fittings: elbows, tees, reducers, crosses, caps and specialty configurations
- High-purity (HP) and ultra-high-purity (UHP) stainless steel tubing and fittings
- Bright annealed (BA) and electropolished (EP) product options
- 304, 304L, 316 and 316L stainless steel options, subject to specification
- Bulk and specialty gas distribution components

- Cleaned, capped and packaged products for controlled installation environments
- Material traceability, MTRs / inspection documentation and project-specific QA documentation
Smithco can source products from leading manufacturers used throughout the semiconductor industry, including Valex and Dockweiler, as well as qualified alternate manufacturers when project specifications and approved-vendor requirements allow. We regularly quote Valex CFOS and HP tube, pipe and fittings, as well as Dockweiler CFOS tube and fittings and CFOS manifolds for bulk and specialty gas systems — always subject to project specifications and approved-vendor requirements. Our team supports material takeoffs, specification review, sourcing, documentation and coordinated project delivery of semiconductor gas piping materials and complete material packages.
Instrumentation
Instrumentation tubing, tube fittings & flow control
Smithco supplies instrumentation tubing, tube fittings and flow-control components for industrial process, semiconductor, chemical, energy and advanced manufacturing applications. Materials and configurations can be supplied to project specifications with required pressure ratings, metallurgy, surface finish, cleanliness, testing, traceability and documentation.
Product scope
- Seamless stainless steel instrumentation tubing
- Compression tube fittings and adapters
- Needle, ball, check and metering valves
- Pressure regulators and gauges
- Instrumentation manifolds and valve assemblies
- Tube-to-pipe adapters and transition fittings
- Mounting, clamps, supports and related accessories
- High-purity instrumentation and clean-service options where specified
Tubing supplied capped and bagged for controlled installation environments.
Smithco can also coordinate instrumentation material packages with mechanical piping and high-purity / CFOS material requirements to simplify procurement and project delivery.
Cleaned, capped and individually bagged product with lot and heat traceability.
Cleanliness & Documentation
Specification-driven from quote to delivery
High-purity work is documentation work. Smithco supports cleanliness requirements, surface finish specifications, material traceability, MTRs and inspection documentation, and project-specific QA requirements as part of the quote — not as an afterthought. From high-purity stainless steel tubing to complete gas-distribution material packages, products arrive cleaned, capped and packaged for controlled installation environments, with the paperwork that lets your quality team accept them.
For material RFQs, bills of material and drawing packages, our estimating team reviews the specification and responds with pricing, availability and lead times — see the full Mechanical Materials & PVF product scope.
