Conventional acid filters cannot remove this contamination and are also significant contributors of harmful metals and fine particulate. ICB® filters eliminate these key issues and direct maintenance to where it matters most. *ICB® is a registered trademark of EPT CLEAN OIL.   [![Download Brochure](https://no-cache.hubspot.com/cta/default/170326/c29c543e-0a61-4501-9d2c-7cad76b383a9.png)](https://cta-redirect.hubspot.com/cta/redirect/170326/c29c543e-0a61-4501-9d2c-7cad76b383a9) Model #ICB-600502 #### Length 11.030 in (28.016 cm) #### Outer Diameter 4.869 in (12.367 cm) #### Inner Diameter 1.866 in (4.740 cm) #### Dry Weight 8.5 lbs (3.9 kg) Model #ICB-600503 #### Length 18.000 in (45.720 cm) #### Outer Diameter 6.211 in (15.776 cm) #### Inner Diameter 2.250 in (5.715 cm) #### Dry Weight 13.0 lbs (5.9 kg) Model #ICB-600504 #### Length 18.000 in (45.720 cm) #### Outer Diameter 6.211 in (15.776 cm) #### Inner Diameter 2.600 in (6.604 cm) #### Dry Weight 13.0 lbs (5.9 kg) Model #ICB-600508 #### Length 32.072 in (81.463 cm) #### Outer Diameter 6.202 in (15.753 cm) #### Inner Diameter 1.555 in (3.950 cm) #### Dry Weight 23.0 lbs (10.4 kg) Model #ICB-600509 #### Length 17.875 in (45.403 cm) #### Outer Diameter 11.045 in (28.054 cm) #### Inner Diameter 2.375 in (6.033 cm) #### Dry Weight 35.0 lbs (15.9 kg) Model #ICB-600510 #### Length 19.010 in (48.285 cm) #### Outer Diameter 11.045 in (28.054 cm) #### Inner Diameter 2.375 in (6.033 cm) #### Dry Weight 37.0 lbs (16.8 kg) Model #ICB-600511 #### Length 19.473 in (49.461 cm) #### Outer Diameter 11.020 in (27.991 cm) #### Inner Diameter 2.375 in (6.033 cm) #### Dry Weight 38.0 lbs (17.2 kg) Model #ICB-600514 #### Length 20.157 in (51.199 cm) #### Outer Diameter 11.045 in (28.054 cm) #### Inner Diameter 2.375 in (6.033 cm) #### Dry Weight 40.0 lbs (18.1 kg) Model #ICB-600524 #### Length 20.157 in (51.199 cm) #### Outer Diameter 11.045 in (28.054 cm) #### Inner Diameter 2.375 in (6.033 cm) #### Dry Weight 40.0 lbs (18.1 kg) Model #ICB-601349 #### Length 24.563 in (62.390 cm) #### Outer Diameter 10.281 in (26.114 cm) #### Inner Diameter 8.919 in (22.654 cm) #### Dry Weight 35.0 lbs (15.9 kg) Model #ICB-601946 #### Length 9.119 in (23.162 cm) #### Outer Diameter 6.211 in (15.776 cm) #### Inner Diameter 2.600 in (6.604 cm) #### Dry Weight 6.0 lbs (2.7 kg) Operating Temperature 86°F to 176°F (30°C to 80°C) Operating Pressure Maximum operating ΔP is <90 psid (<6.2 bard) with normal ΔP <25 psid (<1.8 bard) Materials of Construction #### Shell Stainless steel #### Endcaps Stainless steel #### Handle Stainless steel #### Seals Silicone ICB-600508 utilizes Fluorocarbon gasket standard.
