Second generation ergal cylinder head with two large sealing ORINGs (TC02B).The two large sealing ORINGs dimensions ensure perfect watertightness on all cylinders on the market, managing to adapt perfectly to both those with large and small holes. The central tube is made of stainless steel with a small sealing o-ring and ensures greater mechanical resistance and less friction.The front stop in high density UREPAN is designed to maximize the shock-absorbing effect while maintaining high silence.The size and position of the guide holes ensure contact of the front stop on the internal wall of the gearbox, maximizing the shock-absorbing effect of this head cylinder.The shape of the rear stop in UREPAN favors the conveyance of the air towards the exit hole and reduces the noise due to the firing cycle.Among the excellent characteristics of this new cutting-edge technological material are: - high dynamic load capacity- high resistance to abrasion and impact propagation- highest modulus of elasticity of all elastomers- excellent mechanical resistance to wear- high impact resilience- high thermal resistance at high temperatures UREPAN also offers good chemical resistance to mineral oils and greases as well as various solvents and is recommended for all applications with high demands on load-bearing capacity, resilience in extension, speed and duration. Hardness of the orange rubber = 70 degrees shore which makes it suitable for multipurpose use. Designed for: M4 , M16 , SR16 , MP5 , MC51 , G3 , MINIMI , LR300.
