Usable in high-temperatures of 300ºC vacuum, The leakage of FV-BR1 is still less than a very slight 1.33 × 10-10 Pa · m3/s [He], so it can be used in vacuums with confidence. Usable in high temperatures of 300 °C 572 °F vacuum.

● The leakage of FV-BR1 is still less than a very slight 1.33 × 10-10 Pa · m3/s [He], so it can be used in vacuums with confidence

● Highly resistant to repeated bending
