SEAL TWISTOR helps to reduce the chance of installing damage. It turns seal to an omega shape so as to make the size of seal smaller than the gland diameter. Seal crosses over the sharp chamfers safely then rebounds in the groove. Four different sizes in a set:

S (0.7’’~1.187’’，22~30mm)

M (0.187’’~2’’，30~50mm)

L (2’’~2.75’’，50~70mm)

XL (2.75’’~6.5’’，70~165mm).

Instructions for use:

1. Put one handle into holder, place the seal on the claws

2. Lead the seal with one handle when turning the handle with the other

3. Hold both handles then take them away from the holder

4. Put the seal aside

5. Release a handle then turn it around gently

6. Take Twistor away from the gland smoothly
