Water CSST

Our water CSST is available in 3 different versions – stainless steel, blue, and red polyethylene coated. This helps differentiate between cold and hot water within a distribution system. Just like our gas CSST, the simple 3-step installation process (cut, connect, tighten) makes installation easier and faster than traditional hard pipe systems. General water distribution systems, tankless water heaters, and heat exchangers are some of the applications our water CSST is made for.

  • Lower Labor Costs (vs. Hard Pipe)
  • Flexible, Durable, Lightweight
  • Corrosion-Resistant
  • Patented 3-Step Installation (Fittings)
  • No Special Tools or Equipment Required
  • Blue or Red PE Coating Available
  • Environmentally Friendly Product

Product Testing

Hydrostatic TestInternal hydrostatic pressure increased to 220 ± 7 psi (1516 ± 48 kPa) or 1.5 times the rated pressure, whichever is greater, at the temperature of 68° ± 5° F (20° ± 3° C) for a period of 5 minutes.
Hydrostatic Burst Test"Internal hydrostatic pressure increased to 588 ± 7 psi (4051 ± 48 kPa) or 4 times that rated pressure, whichever is greater, at the temperature of 68° ± 5° F (20° ± 3° C) for a period of 5 minutes.
Bending TestBending motion being applied uniformly at the rate of 5-6 cycles per minute.
Hydraulic Shock TestSubjected to a hydraulic shock for 2,000 cycles at 68° F ± 5° F. The Hydraulic shock shall consist of a sudden increase in pressure from 50 psi (345 kPa) to 284 psi (1967 kPa) lasting 1 second.
Vibration TestFilled with water. The amplitude of vibration was 0.2 inches and the frequency was 25 Hz for 3 hours.
Flattening TestPressed to 2/3 D height of the outer diameter until the tube is flat. No signs of cracks or leakage shall be found.
Impact testAn impact force of 9.76 to 15.19 lbf·ft was applied to various fitting sizes by using a hammer.
Toxicity TestConforms to NSF/ANSI 61 & 372
