Greene, Tweed has extensive experience in designing and manu-facturing Vee rings and seal stacks incorporating elastomeric and/or thermoplastic end and central adapters.
Vee Ring applications require specially developed elastomer and thermoplastic compounds. Below are some compounds and their features.
Thermoplastics utilized include:
When used in open glands, Greene, Tweed designers can accurately control the FSH (free stack height) and CSH (confined stack height) ensuring optimum performance.
Service-proven designs combine elastomer and thermoplastic adapters.
The staging effect of elastomeric and thermoplastic sealing elements gives sealing integrity across a broad range of service conditions.
