When shipping, it is folded finely to about 15 cm and it is packed and delivered. When folded and reached, at the fold part, it glue with the adhesive inside, and dozens of parts that can not be sworn are made. After confirming the delivery method, I will send it without breaking long. In fact, it is folded in detail and arrives in a small box of 60 sizes. If it is in winter, it has already been done with only creases, but from the beginning of the spring it seems that the temperature of the truck is considerably high, the adhesive inside is firmly melted and the folded parts are glued and delivered. So, it does not become usable at all. I need it although I need it today.

Even in underground burial we have a waterproofness when used in duplicate in two sizes. The price is also one tenth as compared with Raychem so it is very profitable.

Insulation and waterproofing when wiring is connected
From Japan

I have been using it for about 20 years, but it is also good with waterproofing and no problem This time, I bought it for the first time at this site, I really wanted a size of 1/8, but it seemed that there was no handling I made it of a different size. Please increase more variations. Also, please do not bend the tube when packing. The ruined place will not return. Please ship it round or long.

The price is somewhat high, but I think that the use feeling is good, the inner adhesive layer is better a little thicker.

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.
