Changzhou Hongxinyutai Precision Mold Co., Ltd. is a dedicated manufacturer of precision injection-molded components for the automotive and energy sectors. Our PP-T30 Injection Molded Electric Vehicle Breather Valve IP68 Submersible for Battery Pack is engineered to provide reliable pressure equalization and ingress protection for EV battery enclosures. With a factory size of 1,000–3,000 square meters and a team of 51–100 experienced professionals, we ensure every valve meets strict quality standards. This product is designed to withstand harsh environments, including complete submersion, while maintaining the integrity of the battery pack.
The breather valve uses a specially formulated PP-T30 material that offers excellent chemical resistance and mechanical strength. It is ideal for electric vehicles, hybrid electric vehicles, and stationary energy storage systems that require a robust venting solution. By allowing trapped gases to escape during pressure changes, the valve prevents deformation and seal failure, thereby extending battery life and enhancing safety.
Key Features & Technical Specifications
- IP68 Submersible Protection: Tested to withstand continuous immersion in water up to 1.5 meters depth for 30 minutes, ensuring reliable operation in wet conditions.
- Material: PP-T30 – High-impact polypropylene with UV stabilizer, flame retardant properties (optional), and excellent resistance to automotive fluids.
- Pressure Equalization: Automatically opens at a set pressure differential (typically 0.5–5 kPa) to release internal pressure, then reseals to prevent moisture ingress.
- Operating Temperature Range: -40°C to +125°C, suitable for extreme climates.
- Compact Design: Dimensions customizable, typical outer diameter 30–60 mm, height 15–30 mm.
- TS16969 Certified: Manufactured under a quality management system that meets automotive industry requirements.
- Easy Installation: Available with push-fit, snap-in, or threaded mounting options.
- Long Service Life: Designed for 10+ years of normal operation with minimal maintenance.

Frequently Asked Questions (FAQ)
Q1: What is the IP68 rating and how does it apply to this valve?
A: IP68 means the valve is dust-tight and can be submerged in water beyond 1 meter depth for a specified time (our standard test: 1.5 meters for 30 minutes). It is suitable for battery packs that may be exposed to rain, washing, or temporary submersion.
Q2: Can this valve be used for other applications besides EV battery packs?
A: Yes, it can be used in any enclosure that requires pressure equalization and water ingress protection, such as solar inverters, LED lighting, and industrial electronics.
Q3: What is the typical lifespan of the PP-T30 breather valve?
A: Under normal operating conditions (temperature range, no chemical attack), the valve is expected to function reliably for 10+ years. The PP-T30 material has good resistance to aging and UV if exposed.
Q4: Is the valve certified for automotive use?
A: Our manufacturing facility is TS16969 certified, which is an automotive quality management system. The valve itself is designed to meet common automotive standards, but specific certifications (e.g., for flammability) can be added upon request.
Q5: Do you offer custom colors or branding?
A: Yes, we can produce the valve in custom colors (e.g., orange, blue) and add your company logo or part number on the surface. Minimum order quantity may apply.
Q6: How does the valve prevent moisture from entering when the vehicle is washed?
A: The valve membrane is designed to be hydrophobic and oleophobic, allowing gas to pass while blocking liquid water. Additionally, the sealing lip ensures no water ingress under normal pressure conditions.
Q7: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is typically 1,000 pieces. For custom designs, MOQ may be higher. We can discuss sample orders for qualification.
Q8: Can I get a sample before placing a bulk order?
A: Yes, we offer samples for testing. Please contact our sales team with your requirements, and we will provide a sample for a nominal fee (refundable for large orders).
