Welding locations must be maintained at least 25 x pipe diameter. If it cannot be achieved, cooling is required to protect the sealing rubber ring: a) Wrap the connection with a cold wet rag; b) Solder first, then clamp and install the pipe after it cools down. PCC PRESS INOX M has complete accessories, generally no need for silver soldering/brazing.
The welding position must be maintained at least 10 × pipe diameter distance. If it cannot be achieved, the protection measures are the same as above: a) Wrap with cold wet rag b) Solder first and then install, cool and then clamp PCC PRESS INOX M Generally there is no need to use soft soldering
Can be used in narrow placesConnected in advance, and then press.
Yes, but try to avoid it. Spin over 5° Must be re-pressed.
It is generally not recommended to mix them (the sealing elements are different). They may be used in the same installation only if both are approved for the same environment.
Yes, suitable for annealed, semi-hard and hard-drawn copper pipes.
It must be a perfect circle, otherwise the accessories cannot be installed. Cutting with a pipe cutter eliminates ovality.
Avoid accessories being too close to nails, frames, mounting clips, etc. to prevent additional stress caused by thermal expansion and contraction.
Yes, but old copper pipes mustNo defects, no scale, clean exterior。
water systemDo not freeze, ice expansion will damage the pipe /系統.
Yes, suitable for emergency repairs. If the water pressure is too high, you can open other faucets to reduce the pressure, and the compression tools must be kept dry.
passstress testVerification, the process is the same as for welded pipe pressure testing.
There are usually only three reasons:
a) Not clamped → Make sure the installation is correct and then replenish the clamp.
b) The copper pipe is not inserted correctly → cut off the fitting and reinstall it
c) The press clamp is misaligned → cut off the accessories and reinstall them
mustReplace sealing ring. Remove the nozzle cape before installation.
No need, no open flame welding, can be repaired directly.
That is, the Smart Connect function is used for quick identification during stress testing.Unclamped connector。
- Air pressure test: 2.2–600 kPa
- Hydrostatic test: 100–600 kPa
After crimping the LBP components are removed, creating a permanent leak-proof connection.
It can quickly identify unstuck pressure points without shutting down the evacuation system, detecting hidden dangers in advance and reducing water leakage losses.
PCC PRESS INOX M / M G sealing ring design life 50 years, safety factor 1.8.
affordable 10–15 metric tons pressure, allowing for larger clamping errors.
- EPDM for drinking water: more than 50 years of use
- HNBR for gases: commonly used in mechanical seals
When installed correctly, the service life is the same as that of copper pipes.
The manufacturer uses approved silicone oil; it can only be used on sitewater. Petroleum-based lubricants (incompatible with EPDM) are strictly prohibited.
- Main body: 316L stainless steel
-Sealing ring:
- Drinking water: EPDM
- Gas: HNBR
- Short time: highest 200°C
- Long time:-20°C ～ 90°C
> 1.3 kN, much higher than AS3688 requirements.
Yes, vacuum pressure 800 kPa, positive pressure performance is better than negative pressure.
No, the sealing ring is incompatible with the refrigerant.
oil concentration25 mg/m³ Available; use PCC PRESS INOX M G when in doubt.
onlyShujie maintenance connection, the geometry is not suitable for the main pipeline.
allowed to be used aselectrical ground conductive。
Long-radius bending and expansion hole design reduce water turbulence and reduce premature wear of the pipeline.
