Frequently Asked Questions
Q: What sizes does this KF vacuum flange clamp come in?
A: This vacuum flange clamp and centering ring set is available in KF10, KF16, KF25, KF40, and KF50 sizes, making it compatible with a wide range of standard vacuum pipeline and chamber fittings used in lab and industrial environments.
Q: What is the difference between NBR and FKM O-ring seals?
A: NBR (Nitrile Butadiene Rubber) O-rings are excellent for general-purpose vacuum applications and are resistant to oils and fuels. FKM (Fluororubber/Viton) O-rings offer superior chemical resistance and perform well at higher temperatures, making them ideal for more demanding laboratory or industrial vacuum systems. Choose the seal material that best suits your specific application requirements.
Q: Is this fitting suitable for homebrewing or food-grade applications?
A: Yes, the KF vacuum flange clamp is popular in homebrewing setups. The 304 stainless steel and aluminum alloy construction offer good durability and cleanliness. However, please verify the specific O-ring material's suitability for your application before use in any food or beverage contact scenario.
Q: What is the maximum pressure rating for this vacuum clamp fitting?
A: This fitting is rated for pressures under 850 kPa, suitable for most standard laboratory, homebrewing, and industrial vacuum processing applications.
