V3
The V3® is designed for coolant vent lines. To guarantee that the product can resist cooling-water, the V3® is made two-parted. The housing is made of materials resistant to cooling water, and the locking ring is made of flexible material. To ensure that you save space, the V3® only has a half locking ring and is designed with an anti-rotation feature.
