New Industrial Style with a Better Grip
The Pacific SF Fittings are forged with Industrial Style Helical Knurling Designed Rotators made with high-quality brass and treated with a special surface finishing, creating a new look with fantastic aesthetics and providing a more ergonomic grip while installing.

Make Building Easy With A Little Help
Pacific SF Extenders come in handy when you need your build to be more user-friendly even after installation, add a 90-degree fitting with an extender under the radiator, and you can make changing coolant an easy thing to do.

Swirl and Adjust
The rotators are 2-way, 360-degree revolvable, bringing convenience during installation and disassembly.
Choose What Fits Best
Pacific SF Extenders come in 20mm to 30mm lengths in several designs of G1/4 screw threads, from male to male, female to male, and female to female, providing a wide range of selections for you to build your liquid cooling system more efficiently.

Cautions
Thermaltake recommends the following steps to be taken before using the Pacific series radiators and water blocks:
- To ensure a clean loop, flush and rinse your radiators and water blocks with distilled water prior to use.
- Do not use tap water or distilled water as your coolant, it may harm your loop and reduce performance.
- It is strongly recommended to use market-proven pre-mix coolant, such as Thermaltake Coolant 1000, which offers great performance while protecting the entire liquid loop from corrosion.
- Before storing your water cooling components, please clean, rinse, and dry. This will ensure a longer lifespan for your components.
Thermaltake recommends the following steps to be taken after completing your water loop setup:
- It is strongly recommended to use market-proven pre-mix coolant, such as Thermaltake Coolant 1000, which offers great performance while preventing corrosion in the entire cooling system (copper, brass, nickel, aluminum, and steel).
- Fill the reservoir with coolant and cycle the power on and off several times while the pump pushes the coolant into the loop.
- DO NOT let the pump run dry. If no liquid is entering the pump, turn off your power immediately.
- Fill the reservoir to the top to prevent air from entering the pump.
- If necessary, tilt the system slightly from side to side to bleed the air out of the loop.
- Place paper towels under fittings and joining points to test for leaks.
- Run the loop with the fill port open for about 24 hours to completely bleed the air out of the loop.
- Before starting, flush out your system properly to prevent any coolant or unwanted particles from sticking to your tubes, radiators, and other cooling components.
- Coolant might fade over time.
