Replace the rubber O-ring with a spring-energized metal C-ring! "Delta Beta HNRV"
"Replace rubber O-ring to metal seal, Eliminate gas permeation and gas release." This can be possible with Delta Beta HNRV.
The Delta Beta HNRV(low load type HELICOFLEX) is originally designed with a low design tightening pressure (Y) and a special processing of the internal spring, achieving replacement of rubber O-rings, performance enhancement, and PFAS-free characteristics. It is a metal seal recommended for those who have concerns such as: "I want to eliminate gas permeation and gas release from vacuum rubber O-rings." "I cannot change the number or size of bolts on existing flanges." "I am troubled by PFAS in rubber O-rings." 【Features】 ■ Mainly for ultra-high vacuum ■ Even lower design tightening pressure than before ■ Can be replaced with elastomer O-rings ■ Two delta-shaped protrusions on the contact side of the cross-section ■ PFAS-free This does not guarantee compatibility with existing flanges. Specifications for existing flanges are required. For more details, please download the PDF or feel free to contact us.
