User questions & answers

Question:	will this work with 110 volt
Answer:	No, they are designed for use in 6volt and 12 volt DC systems such as you'd find on your vehicle. Using them on 110 volt AC is not recommended.
Question:	Is it compatible with al-cu wire
Answer:	It all depends on the size of the wire.
Question:	Would these work with electric sidewalk lighting
Answer:	I would say yes. I used them on a boat motor.
Question:	I don't have a heat gun. Do these need a heat gun to be effective
Answer:	They work just fine if not shrunk down to the wire. You can can use a flame but is a little difficult. Just get a cheap heat gun, , much easier and better.

User questions & answers

Question:	Do these have the adhesive inside as well
Answer:	Wow, so many clueless reviews. Heat shrink can and does contain heat activated adhesive sealant. It does not affect the connection at all, only seals to prevent water intrusion on marine applications such as wiring a bilge pump. I do not know if these have it but you will see a small amount ooze out if it does.
Question:	what temperature is needed to shrink these? Will a hair blow dryer work or is heat gun needed
Answer:	Hair dryer, heat gun, lighter, mini torch all work.
Question:	Are you certified to use them at 120/127 volts
Answer:	Wire size and material determine maximum current and loss due to heat (ignore above comment). Insulation determines maximum voltage. 120 volts is American household voltage. These are designed for marine and automotive applications which are typically 12 volts, sometimes 24 volts, and rarely 48 volts or other voltage. I would verify with manufacturer what the maximum voltage the insulation can take is. I repeat, these are not designed for household use, and I have never heard of those voltages in a marine or automotive application.
Question:	What crimp tool is needed to crimp these
Answer:	Make sure to use a crimped for coated connectors. If you puncture the coating they will no longer be waterproof. If that doesn't matter the regular butt connectors are way cheaper. Use these for wet applications and marine for sure.

User questions & answers

Question:	Is this waterproof? marine grade? thanks
Answer:	Yes, these heat shrink connectors are marine grade. Please note that butt connectors are fully waterproof (water will not get inside the connector, once connector is sealed). Please note that ring, spade, hook and fork connectors have copper elements the are not covered with heat shrink tubing.
Question:	Are these Brazed Seam terminals
Answer:	Yes,They are Brazed-seam terminal connector.
Question:	What's the difference between matte tin-plated red copper and bright tin
Answer:	Bright tin wears out faster.MATTE Tin-Plated Effectively prevent the copper layer rust anti - oxidation.
Question:	What terminal sizes are offered? I need 3/8” and 5/16” for batteries
Answer:	The diameters of the ring connectors in this kit are 3/8, 5/16, 1/4, and 3/16 which should fit the terminals you plan to use. You should also consider wire size before ordering this kit. This kit can be used on wire sizes AWG 22-16, 16-14, and 12-10. If the wire sizes are greater you will need to find a connector built for that wire size as well as the correct diameter of the ring on that connector.

User questions & answers

Question:	Can these be used to pigtail copper to aluminum wiring or will it fail the same as a wire nut
Answer:
Question:	Do you offer these connectors in a similar connection to the solder seal butt connectors
Answer:	Standard wire crimper that has red, blue and yellow dots on them for the different wire sizes would better. You’d better not use those crimpers which are too sharp. It seems that sharp crimper would damage the butt connectors. Hope this would help you
Question:	Can anyone recommend the best ratching crimping tool for this style of insulated connector
Answer:	NO!!!!! 12volt use only

User questions & answers

Question:	The metal portion is copper or aluminum
Answer:	Copper, real good seal when heated.
Question:	where are they made
Answer:	It doesn't say on the package where they are made
Question:	Can they be used in the house
Answer:	I absolutely would NOT try to use these in a home application. Call a certified wiring tech for any in home wiring. They will NOT pass an inspection, let alone protect you from 120volt electric shock. Auto/marine 12volt applications ONLY they are great quality and I have used them to wire multiple vehicles and boats. I am a wiring engineer 20 years, please DO NOT try to use these for your home wiring. Your house could burn down or you could be seriously injured. Look up home wiring supplies, get a electrical tester that tells you if a wire is live! Wire nuts are your better option if your going to use anything, wrap them in electrical tape. Please be safe, consult a professional.
Question:	How good are they I use 3m all the time
Answer:	They seem to seal good I use a crimp tool designed for the heat shrink connectors.
