Installation steps

The key to installing the BSP Male Captive Seal Hollow Hex Hydraulic Plug is "precise torque control" and "protection of the sealing element". The entire process can be divided into three steps.

【1】Preparation before Installation

（1）Cleaning and Inspection: Thoroughly clean the hydraulic ports and the threads of the BSP Male Captive Seal Hollow Hex Hydraulic Plug, removing oil stains, iron filings, and other impurities. Also, check whether the anti-detachment sealing ring on the screw cap is aged, scratched, or deformed.

（2）Prohibit winding of raw material belts: Do not wind any raw material belts or apply sealant on the threads.

【2】The correct installation procedure

（1）Manual pre-tightening: Align the BSP Male Captive Seal Hollow Hex Hydraulic Plug with the hydraulic port and insert it, ensuring that the threads are correct and there is no resistance. Tighten it by hand until it cannot be further tightened.

（2）Torque wrench tightening: Use an internal hexagonal wrench and make sure to use a torque wrench for the final tightening. This is the most crucial step in preventing leakage.

（3）Judgment criterion: Tighten until the sealing ring is in perfect contact with the flat surface of the port.

【3】Torque reference value

Please refer to the following general torque range for BSP straight threads (unit: N·m):

Thread specification (Size)	Recommended torque range (N·m)
G1/8"	14.0 - 16.0
G1/4"	24.0 - 27.0
G3/8"	33.0 - 40.0
G1/2"	44.0 - 50.0
G5/8"	58.0 - 65.0
G3/4"	84.0 - 92.0

【4】Final inspection and testing

After the installation is completed, a leak test should be conducted after the system is pressurized. Use a tissue to wipe around the screw cap and check for any oil stains. If a leak is detected, do not re-tighten it. Instead, remove it to inspect the seal and the threads. If necessary, replace them.
