When the gearbox cycles, the piston assembly is repeatedly slammed against the cylinder head. As a result of this stress, plastic cylinder heads tend to crack and break over time. This cylinder head replaces the stock plastic cylinder head and can withstand the stress created by the strongest of springs.
The dual O-rings provide an excellent seal. Some airsofters try to use Teflon tape on their cylinder heads to increase gearbox compression (which helps your gun run more efficiently), but this modification is not needed with the SHS Cylinder Heads.
