Which one is for gas tanks?

All tanks are made slightly differently. Without knowing the type/specs of the tank, it is hard to say. However, typically tanks are HDPE, LDPE, or PP. We suggest looking at the specifications of your tank to match the plastic. Most of the time it is engraved right into the tank itself. We Highly recommend using JounJip Stainless Steel reinforcing mesh with your weld to make it more stable. If you have any further questions or concerns please don't hesitate to reach out to us at Help@madorganizer.com

The first bullet in the listing you will find the different types of plastic. 7 Different Plastic Types- Covers the 7 most used plastics- Polypropylene, Polyurethene, ABS, Polyethelene, TPO, Nylon, and Polycarbonate. Here are the abbreviations as well in corresponding order. Neutral Colors- clear(PU) black(PP) beige(ABS) white(PE) grey(TPO) ivory(PA) clear(PC) On the package, it explains common uses.

Are these the rods that are used with Jounjip Plastic Welder Boot Tips?

Yes, These particular rods work very well with the boot tips because they can be fed through the hole to melt the plastic. However, They can also be used with the triangle tips. It depends on your preference.

Which would be used for a kayak

Some manufacturers will print the triangle with the number and abbreviation (ie: PP or HDPE) right on the kayak. Most common symbols are shown in the listing and the bullets above explain the full names (ie: Polypropelene for PP). Others you may have to find on the website or contact the Kayak manufacturer.
