BSP Male Captive Seal Plug

More comprehensive and in-depth maintenance is required for the BSP Male Captive Seal Plug, and for critical applications or specific periods, aging components should be replaced preventively.

【1】Replacement of the core sealing components

The sealing ring is the core wear-prone component of the system, and its lifespan is affected by various factors such as material, pressure, and temperature.

（1）Preventive replacement cycle: For FKM material sealing rings, in normal working conditions, it is recommended to perform a preventive replacement every 2-3 years. In harsh environments such as high temperature, high pressure, or strong corrosive media, the replacement frequency should be shortened to once a year or less.

（2）Specific replacement steps:

①System depressurization: Before replacement, make sure the hydraulic system has been completely depressurized.

②Disassembly of old parts: Carefully unscrew the old BSP Male Captive Seal Plug with an internal hex socket wrench. Be careful not to scratch the threads.

③Cleaning and inspection: Thoroughly clean it body and the port threads, and check for any damage to the plug body and the port.

④Replacement of seals: Remove the old anti-detachment seal ring and install a new seal of the same specification as the original. Ensure it is correctly and firmly inserted into the groove without any distortion or misalignment.

⑤Reinstallation: Install the screw back according to the torque value specified by the manufacturer using a torque wrench.

【2】The influence of material properties on maintenance

Different types of BSP Male Captive Seal Plug have different focuses in terms of maintenance.

（1）Carbon Steel: In humid or corrosive environments, extra attention should be paid to rust prevention. Check if the coating is intact; if necessary, apply rust preventive oil.

（2）Stainless Steel: It has strong corrosion resistance. The inspection focus should be on the wear of the threads and mechanical damage.

（3）Brass: Its hardness is relatively low. Special attention should be paid to whether the threads have been damaged due to excessive tightening or incorrect engagement.
