Acid & Alkali Resistant Flame-Retardant Waterproof Junction Box - Screw Cover Type
WBX
Product Introduction
WBX IP67 Waterproof Junction Box
, injection-molded from ABS with a separate base and lid. Flame-retardant and acid- and alkali-resistant, with IP67 dust and water protection for industrial wiring and equipment power distribution.
Screws fasten the lid to the base and compress the gasket for a tight seal, and built-in screw holes let you mount a PCB directly inside. If you need to see inside without opening the box, choose the optional clear PC lid, which is also flame-retardant and acid- and alkali-resistant. Custom colors, logos, cutouts, and accessories are available, along with an internal mounting plate: flame-retardant ABS with mounting holes as standard, or galvanized steel for high-temperature applications. The WBX is RoHS compliant and CE marked, and its flame retardancy has been tested by SGS.
Product Features
- IP67 Dust and Water Protection: Dust-tight and protected against temporary immersion; suitable for outdoor and wet industrial locations
- Flame-Retardant, Acid- and Alkali-Resistant: The housing is flame-retardant, acid- and alkali-resistant, and UV-stabilized. Actual resistance depends on the chemical and its concentration, so send us your operating conditions for review
- Optional Clear PC Lid: Check wiring and indicator lights without opening the box. The clear PC lid is also flame-retardant and acid- and alkali-resistant
- Custom Options: Colors, logos, cutouts, mounting plates, and accessories from one source. The standard ABS mounting plate is flame-retardant, and a galvanized steel plate is available for high-temperature applications

Applications
Industrial Electrical Wiring
IP67 protection and a screw-down cover make it suitable for branch wiring near distribution panels and for protecting cable entries on machinery. The housing is flame-retardant.
Outdoor Control Enclosures
Dust-tight and waterproof, with UV-stabilized ABS, for street lighting controls, EV charging stations, and outdoor automation equipment.
Wet Process Areas with Acid and Alkali Exposure
The acid- and alkali-resistant housing suits wiring in areas exposed to chemical vapor or splash, such as PCB vertical continuous plating (VCP) lines and other wet process equipment. Before you select a model, send us the chemical name and concentration so we can review compatibility.
PCB Mounting
Built-in screw holes let you mount a circuit board directly, which suits control and sensing devices.
FAQ
Q1｜What does IP67 mean for the WBX, and where can I use it?
IP67 means the enclosure is dust-tight (first digit 6) and protected against immersion in water up to 1 meter deep for 30 minutes (second digit 7). The WBX suits outdoor control boxes, machine tools, and other locations exposed to moisture or temporary immersion. IP67 does not cover high-pressure washdown. If your application needs a different rating or has special conditions, send us your requirements.
Q2｜How do I choose between the standard ABS lid and the clear PC lid?
The standard ABS base and lid are flame-retardant and acid- and alkali-resistant, and suit most industrial applications. If you need to check wiring or indicator lights without opening the enclosure, choose the clear PC lid, which has the same flame-retardant and acid- and alkali-resistant properties. The base remains ABS.
Q3｜How resistant is the WBX to acids and alkalis?
Both the ABS and PC materials are acid- and alkali-resistant, but actual resistance varies with the chemical, concentration, temperature, and exposure time. Send us your operating conditions (chemical name, concentration, temperature, and type of exposure, such as vapor, splash, or immersion), and our team will check whether the WBX fits your application.
Q4｜Can I customize cutouts, logos, and the mounting plate?
Yes. We can customize cutout locations and sizes, add your logo, and fit an internal mounting plate. The plate is flame-retardant ABS with mounting holes for securing components as standard, with galvanized steel available for high-temperature applications. Send a dimensional drawing with your RFQ, and we will provide a quote.
Q5｜How does the screw cover maintain the IP67 seal?
A waterproof gasket sits between the base and lid. Tighten all cover screws evenly to keep the seal, because uneven torque can leave gaps. Inspect the gasket periodically and replace it if it shows signs of aging or deformation.
Q6｜What compliance and testing does the WBX have?
The WBX is RoHS compliant and CE marked, and its flame retardancy has been tested by SGS. To request copies of these documents, contact us through the form or by email.
