VHW 3.0 to 4.2 Upgrade Tip Seal
High Temp Viton Tip Seal for the VHW 1.0-3.0 for use with VCB4.2 bowls enabling a perfect and forgiving seal even with some angle at the interface (if used glass on glass with no tip seal as many customers do the seal is functional, but not "perfect" and the VHW must be held straight into the intake and run at a higher temp setting). Shipped via USPS first class if ordered alone or to international customers; via UPS if part of a domestic glass order. Shipping will not be calculated at check-out if ordered alone and is included for domestic orders; International Orders will have additional shipping surcharge depending upon country. Tip seals should be replaced when cracks appear.
