What are the causes of water leaks in mold joints? An explanation of easily overlooked points and countermeasures.
Do you think that 'water leaking from the joint = failure of the joint itself'?
Water leaks in mold temperature control equipment are related to multiple factors, not just the joint body, including O-rings, gaskets, nipples, and hoses.
For example, do you experience any of the following symptoms?
✔ Water leaks only at the moment of connection
✔ Water droplets or seepage around the joint
✔ No improvement even after replacing the gasket
✔ Leaks reoccur in high-temperature equipment
In reality, common causes include:
Hardening of O-rings and gaskets,
Insufficient locking of worn connection parts,
Scratches on the outer circumference of the nipple,
Deterioration or poor tightening of hoses,
Selection of sealing materials unsuitable for the operating environment.
This document provides a detailed explanation of the mechanisms behind water leaks, inspection methods, differences in gasket materials (silicone and Viton), and key points for preventive maintenance.
Additionally, we introduce products that are useful for overall equipment maintenance, such as replacement gaskets compatible with the Parker 200 series, DME-compatible joints, and temperature control hoses.
Please make use of this information to reduce equipment downtime and maintenance costs.
