From Japan

It is using from about 20 years ago, but this is not a problem and may be waterproof This time, was the first to buy. Person of the site, I really size of 1/8 wanted, was in because it was so that there is no handling, of different size ones. Please increase the more variation. At the same, at the time of packing of luggage, do not bend the tube. Tsutsubure was the place is, you will not return to the original. I ask whether the long shipment of remains round.

Insulation of outdoor electrical wiring connections requiring waterproofing
From Japan
On 2009-06-26 10:43:06
Since the shrinkage ratio is about 4: 1, it is very convenient for connecting electric wires with steps. Further, good adhesion can be obtained by heating with internal adhesive, and tensile strength also increases, so that it can be used with confidence. Also, the waterproof effect by the adhesive is enormous.
