cUPC Deep Cup Strainer Assemblies & Core Drain Components
Engineered to meet rigorous North American plumbing code mandates (ASME A112.18.2 / CSA B125.2), offering heavy-duty structural integrity and leak-tight seating for commercial and residential installations.
Deep Cup Strainer Engineering & Supply Chain Architecture
A comprehensive examination of sanitary drain hardware, metallurgical compliance, hydrodynamic filtration efficiency, and risk-mitigated global sourcing.
Deep-Drawn Cup Hydraulics
Unlike shallow stamped strainers, deep cup strainers feature extended volumetric capacity (up to 40% higher waste retention) preventing immediate drainage blockage while maintaining a continuous, non-turbulent fluid outflow under high-volume water discharge.
cUPC & ASME Compliance
Every deep cup strainer body is manufactured under ISO 9001 certified protocols to satisfy ASME A112.18.2 / CSA B125.2 standards. Rigorous thread gauge verification guarantees seamless compatibility with standard 3-1/2" North American sink openings.
Dual-Origin Sourcing
To shield global OEMs and distributors from geopolitical tariffs and regional disruptions, JANA operates dual production complexes in Zhejiang, China (headquarters established 1998) and Kabinburi, Thailand (14,400 m² automated facility).
Forged Solid Brass vs. Stainless Steel Deep Cups
When selecting a China Deep Cup Strainer cUPC Manufacturer & Supplier, enterprise procurement directors must evaluate the structural trade-offs between forged solid brass bodies (such as C37700 or low-lead CW617N) and deep-drawn AISI 304/316 stainless steel assemblies.
Solid brass strainers produced via hot-forging exhibit superior structural rigidity, preventing body deformation under high-torque locknut installation. This is vital in thick quartz, cast iron, or heavy fireclay kitchen sinks where installation torque can exceed standard hand-tight specifications.
Engineering Rule of Thumb: For heavy-duty commercial sinks (4mm+ wall thickness) or high-traffic institutional kitchens, solid brass bodies with deep 304 stainless steel basket inserts provide the optimal combination of thread strength and corrosion immunity against acidic food waste.
De-coding North American cUPC Certification Requirements
The Uniform Plumbing Code (UPC) and Canadian Uniform Plumbing Code (cUPC), administered by IAPMO, set rigorous mechanical performance mandates. Strainer bodies must pass dimensional validation, hydrostatic pressure tests, and material safety audits before entering North American distribution networks.
- ASME A112.18.2 / CSA B125.2: Specifies physical dimensions, thread pitch (typically 1-1/2" NPSM tailpiece connection), flow rates, and resistance to thermal shock.
- NSF/ANSI 61 & NSF 372: Restricts heavy metal leaching, capping lead content at less than 0.25% weighted average across wetted surfaces.
- California AB1953: Mandatory state-level certification required for all residential and commercial drinking water/food prep sanitary fixtures.

Precision Manufacturing Roadmap: From Brass Rod to Boxed SKU
Our integrated production chain ensures total quality control across hydraulic forming, CNC threading, automated polishing, and rigorous quality inspection.
Material Spectrometry
Optical emission spectrometry verifies brass ingot copper/zinc purity and guarantees lead levels remain strictly under 0.25% prior to melting.
Hydraulic Deep Drawing
High-tonnage hydraulic presses stamp 304 stainless steel sheets into seamless deep-drawn cups without wall thinning or structural stress fractures.
Multi-Axis CNC Machining
Automated multi-axis CNC lathes cut precision locknut threads and smooth tailpiece mating surfaces to eliminate installation burrs and alignment leaks.
Robotic Finish & QC
Robotic polishing arms deliver flawless chrome and PVD finishes. 100% of finished lots undergo dimensional, optical, and pressure seal testing.
Strategic Dual-Origin Resilience (China & Thailand Operations)
In response to volatile international trade dynamics and anti-dumping tariffs, JANA operates two manufacturing hubs. Our original headquarters in Yuhuan, Zhejiang, China handles high-volume core forging and engineering innovation. Simultaneously, our 14,400 m² facility in Kabinburi Industrial Zone, Thailand (operational since December 2023) offers international buyers a qualified alternative country-of-origin (COO) for seamless import into the United States, Canada, and European markets with zero tariff penalties.
Tailored Solutions for Commercial & Residential Sectors
Providing OEM/ODM engineered deep cup strainers and drain hardware engineered for specific global market verticals.
Multi-Family & Residential Real Estate
Standardizing on cUPC deep cup strainers with snap-in baskets simplifies maintenance across large residential complexes. Deep baskets prevent food debris from entering P-traps, drastically reducing plumbing service calls for building managers.
Commercial Food Service & Hospitality
Restaurants, hotel kitchens, and cafeterias demand heavy-duty strainers capable of withstanding constant hot grease exposure and caustic cleaning chemicals. Heavy brass bodies coupled with extra-deep baskets maintain optimal flow under continuous washing cycles.
RV, Marine & Modular Home OEMs
Space-constrained mobile kitchens require specialized compact junior duo strainers and deep cup variants that accommodate custom sink bowl depths while ensuring airtight seal performance against vibration during transport.
