Unique dip molding process allows hundreds of design possibilities by varying wall thickness, hardness, inside length and surface texture.
Step 1 — Choose an Inside Diameter (A)
Vented Caps are soft and flexible and an undersized diameter for a tight fit is suggested. For example, if your outside diameter is 0.500", use a 0.437" Vented Cap.
- These caps do not depend on any mechanical devices and are easily applied and removed.
- The caps are designed to vent the gases that build up in sealed environments.
- Vented Caps relieve the vacuum created when a hot product cools.
Step 2 — Choose a Length (B)
Production Vented Caps are available in any length, in 0.062" increments. Minimum length is 0.187". Maximum length is dependent upon the diameter.
- Inside length tolerance is +/- 0.062".
- Inside length is measured along the side wall to the radius of the closed end, not down the center.
Wall Thickness "C" is measured 0.250" from the open end, increasing slightly toward the closed end. Wall tolerance is +/- 0.010".
