W/M Inlet & Drain Hose Manufacturer for Washing Machine Assembly and Service
As a Washing Machine Parts-W/M Inlet &Drain Hose Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
Our W/M inlet and drain hose range is built for the water paths of household washing machines: cold and hot inlet supply, drain discharge, and internal connection between valve, tub and pump. The hoses are supplied as flexible PVC assemblies with end fittings, clamps and protective sleeves matched to the machine interface.
As a China W/M inlet & drain hose manufacturer and supplier, we support washing machine factories, appliance parts distributors, service networks and private-label programs. Each hose is configured around the machine model, connection thread, hose bore, working pressure and routing space rather than sold as a single universal item.
Our Washing Machine Hose Range
PVC Water Inlet Hose
Flexible PVC inlet hose for cold and hot water supply, with threaded female or male connectors, sealing washers and optional stainless steel braiding for higher burst resistance.
Drain Hose Assembly
Corrugated or smooth-bore drain hose sized to the pump outlet, with formed bends, hook ends and clip fittings for tub-to-pump and pump-to-standpipe routing.
Inlet & Drain Hose Kits
Matched kits combining inlet and drain hoses, clamps, washers and installation accessories for aftermarket packs and service replacement programs.
Application Fit Across Washing Machine Platforms
Inlet and drain hoses sit in different working conditions on the same machine. The inlet side sees continuous mains pressure and repeated valve cycling, while the drain side handles intermittent flow, lint, detergent residue and pump vibration. We select wall thickness, reinforcement and fitting type accordingly.
- Front-load washers: longer inlet runs, high-pressure supply, drain hose routed through the cabinet base.
- Top-load washers: compact inlet connections and drain hose with formed hook for tub outlet.
- Twin-tub and semi-automatic machines: larger bore drain hose for gravity discharge and pump-assisted variants.
- Commercial and coin-operated units: reinforced hose construction for higher duty cycles and longer service intervals.
Materials and Critical Specifications
Hose performance depends on compound grade, reinforcement and fitting geometry. We confirm the following variables before quoting, because they determine pressure rating, temperature range and service life.
| Specification | Typical Options | Why It Matters |
|---|---|---|
| Hose material | Flexible PVC, PVC with polyester reinforcement, EPDM blends | Determines flexibility, chemical resistance and temperature tolerance |
| Inner diameter | 8 mm to 25 mm depending on inlet or drain duty | Controls flow rate and drain time |
| Working pressure | Inlet hoses rated for mains supply; drain hoses for gravity and pump discharge | Prevents burst or leakage under supply pressure spikes |
| Temperature range | Cold supply and hot wash variants | Matches wash program temperatures and ambient conditions |
| End fittings | Threaded connectors, quick-connect, barbed inserts, clamps | Ensures leak-free connection to valve, tub and pump |
| Length and routing | Custom cut lengths, formed bends, protective sleeves | Fits cabinet space and avoids kinking or abrasion |
Configuration Options We Build To
Because washing machine platforms differ by brand and region, we configure each hose to the drawing or sample rather than forcing a standard size. The options below cover the majority of requests we receive.
- Hose bore and wall thickness matched to flow and pressure requirements.
- Straight, 45-degree or 90-degree molded ends for tight cabinet routing.
- Threaded connectors in common washing machine thread standards, with rubber sealing washers.
- Corrugated drain hose with formed hook, or smooth hose with separate clip.
- Color options for brand identification and aftermarket packaging.
- Printed or labeled hose for model identification during service.
Quality Control and Acceptance
Our production background includes high-precision slitting and winding equipment and testing equipment used for capacitor manufacturing, and the same discipline applies to the hose range we supply. Incoming PVC compound, reinforcement and fittings are checked against the approved sample before assembly.
- Dimensional check on bore, length, thread and fitting angle.
- Pressure and leak test on inlet hose assemblies.
- Pull test on end fittings and clamp retention.
- Visual inspection for surface defects, kinks and contamination.
- Batch identification for traceability through packing and delivery.
Acceptance criteria are agreed with the customer before production, so the inspection record matches the specification on the purchase order.
Installation, Maintenance and Serviceability
Inlet and drain hoses are wear items. Correct installation protects both the hose and the machine: inlet hoses should be hand-tightened with a new sealing washer, drain hoses should avoid sharp bends and hot surfaces, and both should be routed clear of moving parts.
For service programs, we supply replacement hoses and kits that match the original connection points, so technicians do not need to modify the machine. Spare parts can be packed individually or in bulk, with labels carrying the model reference for stock control.
One-Stop Appliance Parts Supply
W/M inlet and drain hoses are part of a wider washing machine parts range that includes Washing Machine Parts such as gear boxes, drain motors, pumps, motors, clutches, timers, inlet valves, impellers, rubber drain valve cores, rubber seals, tripods and fittings. Customers consolidating appliance parts can also source Refrigerator Parts and Air-Conditioner Parts through the same order.
Our metalized polypropylene film capacitors are produced on high-precision slitting and winding lines with an annual capacity of 10 million pieces, and are exported to the Middle East, Africa, South America and Southeast Asia. That manufacturing and export experience supports the appliance parts business, where each employee works directly with the market to meet fragmented and personalized requirements quickly.

Frequently Asked Questions
Can you produce inlet and drain hoses to our drawing or sample?
Yes. We configure hose bore, length, fitting type, thread and color from your drawing or physical sample. A sample is the most reliable reference because it captures the exact connector geometry and routing shape.
What materials are used for the hoses?
Our washing machine inlet and drain hoses are typically made from flexible PVC, with reinforced PVC available for higher pressure or longer service life. Material grade is selected against the water temperature, supply pressure and detergent exposure of the application.
Do you supply complete hose kits with clamps and washers?
We supply hose assemblies and can include clamps, sealing washers and installation accessories as a matched kit. Kits are packed for retail, service or bulk production use depending on your program.
How do you control quality on hose orders?
We check incoming material, dimensions, fitting retention and leak performance against the approved sample, and keep batch identification for traceability. Acceptance criteria are agreed before production so inspection matches the order specification.
Can we combine hose orders with other appliance parts?
Yes. Inlet and drain hoses can be ordered together with other washing machine parts, refrigerator parts and air conditioner parts, which reduces the number of suppliers and shipments in a procurement program.
What information should we send for a quotation?
Send the machine model, hose function, dimensions, thread and fitting details, working conditions, material preference, quantity and packaging requirement. A drawing or sample lets us confirm the configuration and prepare the quotation without repeated clarification.
