● Frequently Asked Questions (FAQ)

Q1: What certifications do your vent plugs carry for international markets?

A1: Our products hold IP68, CE, CCC, UL, REACH, TUV, and RoHS certifications. They comply with global standards and are suitable for export to Europe, North America, Southeast Asia, and the Middle East.

Q2: Do you support customized manufacturing for specific colors or logos?

A2: Yes, we are an integrated manufacturer with in-house R&D and mold teams. We support OEM/ODM customization regarding size, material, logo, and color.

Q3: How do I choose the correct thread size for my enclosure?

A3: You should match the thread type (M/PG/G/NPT) and mounting hole size. For example, an M12 vent plug requires a 12mm mounting hole. We offer sizes ranging from M5 to M24.

Q4: What is the operating temperature range for these nylon vent plugs?

A4: Our air vent plugs are designed to operate between -40ºC and 100ºC, with short-term resistance up to 125ºC, making them suitable for most industrial environments.

Q5: Can you provide samples for testing before bulk orders?

A5: Yes, samples are available for testing. We maintain a strict quality control system from raw material to finished products to ensure mass production consistency.

Q6: What is the primary function of the e-PTFE membrane?

A6: The e-PTFE membrane allows air and moisture to escape while preventing water, dust, and salts from entering the enclosure, maintaining a balanced internal pressure.
