IP67/68 Pressure Vent | Electronic Wearable Device

IPRO Home Application Portable Electronics VentsSmart Wearable Device Pressure Vent IP67 IP68 (2m*30min)

IP67 IP68 (2m*30min)

The proportion of smart wearable products, such as smart bracelets, watches and TWS earphones has gradually increased.

Diversified application scenarios have given rise to a strong demand for waterproof smart wearable products. With natural hydrophobic properties base on its multi-fluorine molecular structure, IPRO pressure vent is mainly made of ePTFE and installed at the pressure relief hole of wearable products to equalize pressure. The IPRO Pressure Vent with IPX7 and IPX8 waterproof levels enable the wearable product to be immersed in a water depth of 1 to 2meters for 0.5 to 2 hours without breaking.

Product Application : IP67 IP68 (2m*30min)


With the popularity of intelligent wearable products, traditional wearable products (such as mechanical watches, etc.) are gradually being replaced. Smart wearables have also derived from single-function bracelets into a variety of products, including smart sports watch, children’s watch, TWS headphones, and health monitoring watch for the elderly, etc.


Wearable products are used daily and widely, thus are inevitably exposed to hand sanitizers, sweats, rainwater, and other liquids. Therefore, being waterproof and resistant to corrosive liquids becomes vital for wearable products. In order to achieve excellent waterproof levels, the product must be completely sealed. Yet this creates another problem, i.e., heat generated by electronic components were unable to dissipate, leading to raising temperate and pressure, which prevents the speaker from functioning normally. Meanwhile, pressure may cause damage to the components and the sealing structures as well.


With natural hydrophobic properties and amazing porosity, ePTFE pressure vent is both waterproof and breathable, which helps wearable products to stand against immersions at various depth. For instance, the product can be immersed in water at a depth of 1 to 2m for 0.5-2 hours without breaking. Meanwhile, good air permeability allows the product to have good venting performance, even when sealed completely. Equalizing pressure in time could also protect the internal components and the sealing structures. Moreover, it can prevent the speaker from vibrating poorly, and ensure the smooth tone of the product.


With the waterproof and venting protection, consumers will no longer worry about damage from water to the smart phone.
