Made of strong and durable PVC and packaged in pre-cut 40" lengths--typically enough for a single CPU system
Pre-cut 1 meter length. One length is typically sufficient for a single CPU cooling circuit depending on how tight the coils are wrapped around the tubing.

Note: Two lengths may be necessary for a complete circuit including dual CPU, CPU+VGA, or CPU+VGA+Chipset setups.
3/4" will fit 3/4in O.D. tubing, 5/8" will fit 5/8 OD Tubing, 1/2"" will fit 3/8/1/2 (10mm/13mm) OD Tubing.
Inexpensive mod for a fresh new look!
