[For the semiconductor industry] Replacement of rubber O-rings with spring-loaded C-rings HNRV
No need to change the size or number of existing bolts? A must-see for those struggling with "wanting to eliminate gas permeation and gas release from vacuum rubber O-rings" in semiconductor manufacturing equipment!
Our "Delta Beta HNRV" is a combination of a delta seal designed with a low tightening pressure (Y) and a specially processed internal spring, achieving replacement of rubber O-rings, performance enhancement, and PFAS-free status. For those who have concerns such as: "I want to eliminate gas permeation and gas release from rubber O-rings." "I cannot change the number or size of bolts on existing flanges." "I am troubled by PFAS in rubber O-rings." This metal seal is recommended. 【Features】 ■ Mainly for ultra-high vacuum applications ■ 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.
