Alpha FIT® Heat Shrink Tubing Products

Alpha FIT® Heat Shrink Tubing is incredibly popular nowadays thanks to its many advantages. Especially made for wirings, the product is easy enough to use for DIY projects and is incredibly versatile. For those who want to find out if this product is best for them, following are some of the advantages of this tubing type.

Very Durable

This type of tubing is incredibly durable whether it’s exposed to extreme heat or moist surfaces. This makes it perfect for basement wirings, ensuring that homeowners wouldn’t have to worry about the tubing deteriorating due to the wetness. What’s even better is that this product doesn’t decay overtime and comes with an extra layer of tubing to protect against unpredicted pressure. Compared to traditional tubing methods, the heat shrinking type can last considerably longer, providing a very cheap cost per year. The tubing is also capable of resisting mold growth and even corrosion.

Safe to Use

As previously mentioned, the Alpha FIT® Heat Shrink Tubing comes with an extra layer of protection, significantly boosting its safety level. Specially made for insulation purposes, the product has incredibly high resistance against electrical impulses. This is perhaps why tubing is perfect for DIY projects. The extra level of protection makes it possible for inexperienced electricians to plan their own wirings without too much of a risk.

Perfect Fit

The biggest attraction of heat shrink tubing is the fact that it allows easy fitting on various components. The capacity of the tube to shrink provides an excellent sealant, ensuring that the tubing will cover all the important parts while sliding over the large objects.

How to Choose One

There are various considerations people must take into account when buying heat shrink tubing. Aside from the obvious requirements like voltage ratings and temperature capabilities, the product must have the perfect fit.

When determining the size, buyers must look closely at the shrink ratio. This refers to how small the tubing will be once it is exposed to heat. For example, a 6:1 ratio means that the tubing is 6 times larger than it would be once it starts to shrink. The ratios range from 6:1 to 2:1, allowing users to find the best size that is needed for their project.

Of course, also take note of the voltage and heat requirements mentioned above. Buyers should first consider exactly where they intend to install the tubing and the environmental factors in that situation. This way, they will be able to pick the best type that would fit their needs.

Alpha FIT® Heat Shrink Tubing is mostly used for wire insulation, protection against conductors, for water-proofing, for wire repair, covering against wires and cables as well as an abrasion resistance. Note that although it is incredibly easy to use, working with electricity still poses risks to the individual. This is why when it comes to complicated wirings, it is advised that people use the service of an electrician and utilize the heat shrink tubing for long-term protection against any problems.

Alpha FIT Heat Shrink Tubing Polyolefin and PVC

Alpha Wire engineers and manufactures heat shrink tubing to best fit their Xtra Guard electronic cables and many of their other products. Their brand name is FIT® shrinkable tubing which is a very advanced type of tubing compared to traditional polyolefin and PVC shrinkable tubing.

The most basic 2 to 1 polyolefin shrink tubing is Alpha’s part number FIT 221. It commonly used for general purpose repairs, wire and cable harnessing and cable and connector protection. The Alpha FIT 750 is a similar version with an adhesive inner lining to adhere much better to the application. The FIT 221 version also comes in a FIT 221V that makes it flame retardant to the UL VW-1 and CSA OFT flame retardancy approvals.

There are also a few options for 3 to 1 and 4 to 1 shrink ratios that allow the tubing to shrink down to different diameters for odd shapes that need tubing. Sometimes a cable is 1″ in diameter with a connector over it that’s 2″ in diameter which means it will need a tubing that can shrink down to 2″ and 1″ for a nice fit to both parts. An Alpha Wire FIT 321 tubing in 3″ will shrink as far down as 1″ giving the connector and cable a snug fit.

There are about 20 different types of FIT heat shrink tubing in Alpha’s catalog that offer water resistance, chemical resistance, protection and repair, splice protection, underground splice protection and temperature ratings reaching over 250°C.

The bulk of FIT tubing is irradiated polyolefin and PVC, but there’s also an FEP and TFE tubing available that offers shrink ratios of 1.2 to 1 and 1.5 to 1. This is high temperature shrink tubing in 200°C and 250°C which is commonly used for fiber optic applications, high temperature wire and cable, digital electronics and extremely caustic environments.
