Catalog values are selection references. Performance, compatibility, availability and finished-set suitability remain subject to exact-REF review.
Two supply routes
Buy the component—or ask BQ+ to build the finished fluid path.
The same molded part can enter different projects, but its suitability cannot be assumed outside the selected configuration.
Choose the commercial route after technical matching.
Manufacturers can begin with a component need. Brands and project owners can begin with the complete fluid path.
Component-only supplyExact component REF, drawing, interface, material, packaging and volume.
Finished-set integrationComplete BOM, assembly interaction, testing, packaging and project evidence.

Configuration-specific evidence
Evidence belongs to the exact component and assembled system.
The page helps buyers identify a route; it does not convert representative photographs into family-wide performance or regulatory claims.
- Controlled dimensions and tolerances
- Materials and fluid-contact definition
- Leakage and connection integrity
- Flow, valve or filter function as applicable
- Assembly and finished-set interaction
- Packaging, status and supply documentation
Release boundary: values, availability, regulatory wording and finished-set suitability require the exact BQ+ REF, current controlled evidence and specialist approval.

FAQ
Questions manufacturer buyers ask.
Can we purchase individual components without ordering a finished set?
Selected components can be evaluated for component-only supply. The exact REF, supply status, interface, packaging and commercial terms must be confirmed.
Can BQ+ work from our sample or drawing?
Yes, a sample or drawing can begin comparison. Visual similarity alone does not establish equivalence; dimensional and functional review is still required.
Can the same component be integrated into a BQ+ finished set?
Potentially, but the complete fluid path, assembly interaction and finished-set evidence must be reviewed before release.
Are all variants shown on this page?
No. The page shows representative, traceable product photographs from the current component library. Additional variants are reviewed after the buyer identifies the relevant family.
