The Seal Stretcher enables you to stretch a heated PTFE ring to a desired size. Once stretched the piston seal can be placed on the groove and secured in place with the Seal Clasper. This makes for an easier process of fitting the seal into the cylinder after constriction.
- Put PTFE ring in a temperature controlled oven, heat it up to 120c to soften the PTFE ring.
- Place the headed PTFE ring on a suitable position of STRETCHER then press firmly and smoothly. This will stretch the seal to the desired size.
- Lay the piston seal on to the groove of piston. Clasp it back into the metal groove by using SEAL CLASPER.
- Piston can be inserted in to cylinder easily and safely after constricting.
