Second generation cylinder head in ergal with two large sealing ORINGs (TC02A).The two large sealing ORINGs ensure a perfect watertight seal on all cylinders on the market, managing to adapt perfectly both to those with large or 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 cylinder head.The shape of the rear stop in UREPAN favors the conveyance of 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- resilience high impact- 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 in terms of load capacity, extension resilience, speed and durability. Hardness of the red colored rubber = 80 degrees shore which makes it ideal for overjoule springs and fast gusts. Designed for: M4, M16, SR16, MP5, MC51, G3, MINIMI, LR300.
