About this series

BSL identifies the tower-type pneumatic exhaust silencer group. These components are also described as pneumatic mufflers. Start with the reference and confirm thread compatibility and exhaust requirements; no tested noise-reduction rating is specified here.

Listed model references

These are original model or specification references for an inquiry, not a stock or compatibility guarantee. Confirm dimensions and thread standards before ordering.

The original notation is retained, including Chinese size labels. Do not infer BSP, NPT or another thread standard from the numeric suffix alone.
