PrimoChill CTR™ (Compression Tube Reservoir) System Phase II is the latest in a slew of new products that PrimoChill is catering towards the modders and their need for color!!! What makes the NEW CTRs so unique and not like anything on the market today is the ingenious compression ring end caps that make a water tight seal without the need to cut or tap the end of the reservoir. Similar to the PrimoChill Rigid fittings, the CTR Phase II uses the same principal for securing and sealing off the acrylic tube with little to no force on the tube which prevents cracking. CTRs are the next best thing in the water cooling industry giving the user the flexibility of color as well as sizes to fit their build perfectly. CTRs are certain to be copied, but remember that PrimoChill's are Made in the USA, by Americans..

If a shipped order is refused or returned undelivered, there will be a mandatory 20% restocking fee, a $20.00 Return Service Fee, and no refund on the shipping cost. Please be aware that refusal is significantly more expensive than using your own carrier and is NOT recommended.
