Q:There are several ways to connect the built-in rubber stop
Is the cold adhesive rubber zhishuidai special cold glue, overlapped by the waterstop joints with grinder grinding section to 5~10 cm, glue can be compacted, has high strength, fast solidification has the advantages of convenient, time-saving, can meet the general engineering quality requirements.
Q:What do you mean by "DN" on hydraulic hose?
Hydraulic hose temperature: -40 ~ 120 DEG C, product specification range: DN2.5mm ~ DN305mm.
