Seal stretcher [o40MM-250MM]

SEAL STRETCHER is a professional tool designed for expanding PTFE piston seals prior to installation on pistons with diameters ranging from 40 to 250 mm. It enables controlled stretching of the seal without damaging or permanently deforming it. Due to the low elasticity of PTFE materials, a stretching tool is essential to safely mount the seal without causing microcracks or stress to the ring. The SEAL STRETCHER ensures a smooth and reliable installation process, especially in hydraulic cylinder maintenance. Key Benefits: quick and safe seal expansion avoids seal damage during installation durable construction for workshop and industrial use Applications: PTFE piston seal mounting hydraulic cylinder servicing industrial machine repair workshops
