User questions & answers

Question:	Do you offer larger than 250 count sets
Answer:	Yes
Question:	is it possible to connect 3 wires together with these
Answer:	Hello friend, thank you for your question. We are sorry to tell you that 3 wires could not be connected with one of these solder butt connector. It would be better for you to connect 2 wires with one connector. Hope this would help you. If you have any additional questions, please feel free to let us seller know. We would try our best to assist you. Thanks:)
Question:	Is this what I'd use to wire my KC lights to the stock fog lights wiring
Answer:	Yes, solder seal wire connectors are an excellent choice.
Question:	What temperature should someone use to melt the solder but not burn the waterproof plastic/shrink wrap
Answer:	I USED LOW TEMP SETTING ON MY HEAT GUN.. BUT I WATCHED CLOSELY TO SEE WHEN THE SOLDER MELTED AND PROMPTLY REMOVED HEAT. WORKED WELL.

User questions & answers

Question:	Can you use solid wire too
Answer:	Sure
Question:	What is the amperage rating when rated at 240V
Answer:	Depends more on the wire size, but I would think less than the wire itself unless you mechanically twist the joint, too. Solder as the primary conductor in the joint isn't the best if the joint is likely to get heated by the current.
Question:	Do you crimp these or just twist the wires together and heat shrink them? if no crimping, how strong is it compared to crimping and heat shrinking
Answer:	You will just need to twist the wires together and heat shrink them. Solder inside the connector will melt and bond the wires together. The connection is almost as strong as crimping and heat shrinking. When heat is applied, polyolefin tubing reduces in size and adhesive flows inside the insulation, creating a strong seal
Question:	What temp do I use on the heat gun
Answer:	Low flame

User questions & answers

Question:	Is this heat shrink or just crimped
Answer:	As the description states, these are crimp type connectors
Question:	What is the difference between 'crimp" and 'Heat shrink. And how do you do heat shrink
Answer:	When crimping, you use a plier-like tool to squeeze the metal cylinder around the wire. Thus, you do not have to solder, & if insulated connector you do not have to tape. Heat shrink is a hollow tube, like a drinking straw, that you place the wire inside of and then by using a heat source, aimed at the tubing, you cause the hollow tube to shrink smaller, around the wire it covers to insulate it.
Question:	Are these ul rated for cu/al connections
Answer:	no
Question:	Can I use these on 22 gauge wire for led strip lighting
Answer:	Yes, these connectors support 16-22 gauge wire. Like all connectors, ensure you use sufficient pressure for positive crimp. As always, avoid wet/moist areas where water/liquids might migrate into connector.

Question:	What does AWG means
Answer:	American wire gauge. Match the appropriate connector with gauge of wire you’re using.
Question:	Can they be used for electrical wiring eg, lighting fixtures ac? or just for dc 12 to 24 volts, car and motorbike fittings etc? thank you
Answer:	Yes they can be used on anything I've used mine on a jet ski and trailer now all waterproof ，solder seal wire connectors is really easy to use，but Never use for high voltage
Question:	I don’t have a heat gun, is there anything else I can use the solder connectors
Answer:	You can try to use a lighter which works if you are very careful. but The prefered method is the heat gun.
