Durability and Strength : The Aluminum Alloy construction of the compression ring ensures long-lasting performance, as it is highly resistant to wear, corrosion, and damage. This provides greater longevity compared to plastic alternatives. 

Compatible with Proteam Vacuum Models 10002, 100104, 101338, 106290, 106293 ; Compatible with Cirrus Vacuum Models CR9100, CR67C, CR77C, ProGrade P8000, P8500, P8500A, P9000 

Secure and Tight Seal : The design of the compression ring ensures a secure, airtight seal during operation, improving the overall vacuum performance. This is essential for maintaining suction power and preventing air leaks. 

Improved Vacuum Efficiency : By ensuring a strong seal, the vacuum part helps maintain consistent vacuum pressure, which enhances cleaning efficiency and reduces the need for frequent maintenance or adjustments. 

Corrosion Resistance : Aluminum Alloy is resistant to rust and corrosion, which is critical for maintaining the vacuum's performance in damp or high-humidity environments. This feature enhances the product's lifespan and reliability over time.
