PVC-U Underground Cable
Protection Systems
MDPE (φ 25 to φ 200)
for Gas Plumbing
For water supply:
Products conform to Japanese Industrial Standards JIS K6742.
Impact-resistant PVC-U pipes
For water supply:
Products conform to Japanese Industrial Standards JIS K6743.
Impact-resistant PVC-U fittings
For water supply pipes inside buildings and for piping in cold areas
These products are highly impact resistant even under low temperatures(low outdoor air temperatures) and minimize impact-induced damage during the cold season and when other plumbing work is conducted nearby.
Operating temperature and pressure
| Operating temperature range |
Normal temperature (5 to 35°C) |
|---|---|
| Operating pressure (hydrostatic pressure) |
0.75MPa |
Note that the water-hammer pressure becomes greater as the pipe flow velocity increases.
(Make sure that the pipe flow velocity does not exceed 2 m/sec as a general rule.)
The transparent body enables to check the joint condition. It prevents plumbers from forgetting to apply adhesive.
*Note: It may be difficult to insert the pipe all the way to the stopper depending on the type of fitting.
In that case, insert the pipe to the following position: Zero point + Min. 1/3 ℓ.
Available diameters (nominal diameters): 13mm to 50mm
Products conform to Japanese Industrial Standards
JIS K6776/6777.
Thermal-resistant PVC-C pipes and fittings
Lightweight and thermal-resistant pipes suitable
for hot water supply
These pipes are made from polyvinyl chloride and offer high corrosion resistance and excellent workability for hot water supply. Unlike metal pipes, these products eliminate the water quality degradation, electrolytic corrosion and electrical leakage accidents due to rusting or corrosion.
Operating temperature and pressure
●Nominal diameters of 50 and less

*1. Continuous normal operating temperature: maximum of 85°C for pipes with nominal diameters 50 and less, maximum of 80°C for pipes with nominal diameters 65 and more
*2. Maximum operating pressure: Hydrostatic pressure + Water-hammer pressure
The transparent body enables to check the joint condition.
●It prevents plumbers from forgetting to apply adhesive and from not inserting the pipe all the way!
