The two large sealing O-rings ensure a perfect seal on all cylinders on the market, managing to adapt perfectly to those with both 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 high-density UREPAN front stop 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 shoulder on the internal wall of the gearbox, maximising the damping effect of this cylinder head. The shape of the rear UREPAN stop promotes the conveyance of air towards the outlet hole and reduces the noise due to the firing cycle. Among the excellent features of this new cutting-edge technological material are:
- high dynamic load capacity - high resistance to abrasion and impact propagation - maximum modulus of elasticity of all elastomers - excellent mechanical resistance to wear - high impact resilience - high thermal resistance to 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, resilience in extension, speed and durability.
Red rubber hardness = 80 shore degrees making it ideal for overjoule springs and fast bursts.
