One Supplier for Multi-SKU Hydraulic Fitting Orders

Distributor and OEM orders often include multiple fitting standards, sizes, body styles, and hose-end configurations rather than a single product. Topa helps buyers consolidate these requirements into one purchasing program, making quotation, specification control, packaging, and repeat replenishment easier to manage.

Mixed Product Categories

Combine JIC, BSP, NPT, ORFS, Metric, SAE, hose fittings, adapters, and related hydraulic products in one order.

Multiple Sizes & Configurations

Purchase different thread sizes, dash sizes, straight, 45°, 90°, tee, male, female, and swivel configurations together.

Organized SKU Packaging

Products can be separated and identified by SKU, label, bag, inner box, or carton according to your inventory requirements.

Repeat Order Management

Approved specifications, part numbers, packaging, and order history can be maintained to support future replenishment.

Hydraulic Fitting Manufacturing Process

At Topa, we employ advanced CNC machining to produce our Hydraulic JIC fittings with precision. The manufacturing process includes raw material selection, CNC turning and milling, threading, and final quality inspection. Each fitting undergoes stringent testing for dimensional accuracy and pressure tolerance. Once finished, the fittings are carefully cleaned and prepared for shipping.

Raw Material Area

Material Selection

Raw materials are checked before production to confirm material type, appearance, and basic specification requirements. For qualified projects, material-related documents can also be reviewed according to customer or order requirements.

crimp Fitting Material cut

Cutting & Forging

Raw material is cut to the required size and prepared for forging or further machining. Forged blanks are formed according to the fitting body design to provide the basic shape and strength required for subsequent processing.

JIC Fitting Thread grill

CNC Machining

CNC machining is used to produce the main body dimensions, hex sections, internal bores, shoulders, and connection features. Machining programs and inspection requirements help maintain consistency across different SKUs and production batches.

CNC thread machining hydraulic fitting

Thread & Sealing Surface Machining

Threads, flare seats, cones, O-ring grooves, and other sealing surfaces are machined according to the required connection standard. These areas are critical to installation, sealing performance, and interchangeability.

galvanized Hydraulic fittings

Surface Treatment

After machining and cleaning, fittings receive the required surface treatment according to material, corrosion-resistance needs, and customer specifications. Carbon steel fittings commonly use zinc-based finishes, while other coating requirements can be reviewed for qualified orders.

Quality Test

From material verification to pressure testing, each inspection step focuses on the critical characteristics that affect fitting compatibility, sealing performance, corrosion resistance, and repeat-order consistency.

Hardness Testing

Material and hardness checks help confirm that fittings meet the specified material and mechanical requirements before or during production.

Thread Inspection

Thread size, pitch, profile, and gauge fit are checked to help ensure correct assembly and connection compatibility.

Dimensional Inspection

Critical fitting dimensions are measured against approved drawings or specifications using suitable measuring tools. CMM inspection can be used for selected parts requiring more detailed geometric verification.

Visual & Surface Inspection

Finished fittings are checked for damaged threads, burrs, contamination, plating defects, scratches, and other visible conditions that may affect assembly, sealing, or appearance.

Corrosion Resistance Testing

Salt spray testing can be used to evaluate the corrosion resistance of selected plated or coated fittings according to specified coating and test requirements.

Pressure, Leakage & Burst Testing

Selected hydraulic fittings are tested under defined pressure conditions to evaluate sealing integrity, structural strength, and pressure performance according to product or project requirements.

Request Quality & Inspection Details

Consistency Across Every Repeat Order

For distributors and OEM buyers, sample approval is only the first step. Repeat orders need the same dimensions, threads, sealing surfaces, materials, finishes, markings, and packaging specifications over time.

Consistency Across Every Repeat Order
  • Approved Specifications

Confirmed drawings, dimensions, thread standards, sealing details, materials, surface finishes, markings, and packaging requirements can be recorded before volume production begins.

  • Batch Inspection

Key product characteristics are checked during production and final inspection to help ensure that each batch follows the approved specification.

  • SKU Identification

Part numbers, labels, bags, inner boxes, cartons, and customer-specific identification can be organized by SKU to reduce mixing errors during packing, receiving, and inventory management.

  • Repeat Order Records

Approved product and packaging requirements can be referenced for future replenishment, helping reduce repeated specification confirmation and maintain continuity across recurring orders.
