Bronze Fittings
C89833 Lead-Free Bronze Fittings
A lead-free cast copper alloy considered for fittings, flanges and valve parts where lead content in wetted components is restricted.
Product overview
C89833 fittings are discussed where lead content in wetted parts must be restricted. Applicable regulation, certification and configurations are confirmed with the company; no compliance is claimed on this page.
C89833 belongs to the family of lead-free cast bronzes developed to replace leaded alloys such as C83600 in applications where lead content is restricted – notably in potable-water and similar services. Machinability in these alloys is achieved through additions other than lead.
Whether a particular casting meets a drinking-water requirement depends on the applicable regulation, the exact composition, the product design and any third-party certification. This site does not claim compliance with any such scheme; those details must be verified with the company and the end-use regulator.

Machining and fabrication
Designed to machine acceptably without lead; machinability differs from leaded alloys, so tooling and speeds should be reviewed. Casting soundness and pressure tightness are central to this grade’s use in fittings.
Forms and sizes
- Elbows (45° and 90°)
- Tees and crosses
- Couplings and reducers
- Unions, plugs and caps
- Custom fittings to drawing
Only fitting types technically appropriate to the material, application and manufacturing method are offered. Sizes, thread forms and ratings are confirmed with the company. Do not rely on this page for dimensions, tolerances or stock.
What to include in your inquiry
- UNS grade and governing specification
- Dimensions (or drawing) and tolerance class
- Quantity and delivery timing
- Application and operating environment
- Certificate / inspection requirements
Composition reference
Composition limits for C89833 are not reproduced here pending technical review against the current edition of the applicable specification. They will be added once verified.
Commonly referenced specifications
- Applicable ASTM specification and any drinking-water compliance scheme (for example NSF/ANSI 61 and 372, or local equivalents) to be confirmed with the company

Frequently asked questions
Does C89833 meet NSF/ANSI 61 or 372?
This website makes no certification claim. Compliance depends on the product and any third-party listing, which must be confirmed directly with the company.
Can I swap C89833 for C83600?
Not automatically. Properties, casting behaviour and dimensions should be reviewed against your specification.
