Did you know?

PTFE, also known by the DuPont trade name Teflon®, was accidentally discovered in 1938 by a scientist named Roy Plunkett in an attempt to create a new form of Freon refrigerant by reacting hydrochloric acid with a little known compound called tetrafluoroethylene (TFE). Plunkett discovered that instead of producing the desired gas, the TFE had polymerized into a white, flaky powder. Initially, the value of this substance wasn’t clear to Plunkett, however it came to use in World War II during the development of the Atomic Bomb. Making the bomb required scientists to handle large amounts of the caustic and toxic substance uranium hexafluoride, and PTFE-coated gaskets and liners were able to resist it’s extreme corrosive action. PTFE is inert to virtually all chemicals, and is considered one of the most slippery materials in existence. These properties have made it one of the most valuable and versatile technologies ever invented, contributing to significant advancements in areas such as aerospace, communications, electronics, industrial processes and architecture.

Today, the majority of PTFE (roughly 50% of all production) is used for aerospace and other high-performance electrical wiring applications. The superior dielectric properties of PTFE makes it an ideal insulator for wire & cable used in connector assemblies as well as printed circuit boards operating at microwave frequencies.

Audible Passion

Whitmor/Wirenetics is a leading provider of high-performance wire, cable, and tubing products. We have served the military, aerospace, and satellite industries for over 50 years. With our proven experience we found a niche in an industry that needed to be filled; dedication to offering our products and services for guitar and other musical instruments.

As musicians, we really are a picky bunch, but for good reason. After all, our audiences will not sit through a shoddy performance, so why should we use shoddy gear? We choose gear that can withstand the rigors of stage use and abuse, but we also choose gear which allows us to best express our artistic vision; gear which is built by skilled artisans who know their craft well.

Audible Passion?

MAGNE-TONE plain enamel magnet wire for guitar pickupsWe really do share your passion for musical instruments – the electric guitar, electric bass, the tube (valve) amplifier – all tools which help us translate our innermost emotions into an audible, tangible reality.

We can know by the very composition of a cable or by the type of enamel in magnet wire which musical tone we should expect. It’s not all that difficult, really. For example, a pickup winder knows which type of magnet wire belongs in each variety of pickup; by using Plain Enamel magnet wire in PAF-style pickups to Heavy Formvar in 1950’s single coils, a certain musical tone is produced, which then achieves the desired end result.

Whether it is the magnet wire used to wind guitar pickup coils to vintage cloth “pushback” wire that connects the pickups to the various components, or even the cable that connects the guitar to the amplifier — including the heat shrink tubing that protects the plug housing — we want to bring American-made high quality components to an industry that shares our passion: the pursuit of excellent musical tone.

Product Spotlight: ELECTRI-TONE® Guitar Wire and Cable

From vintage cotton braided “pushback” wire used in guitars and tube amplifiers to multi-conductor lead cable to heat shrink tubing and MAGNE-TONE® magnet wire for guitar pickups, our new ELECTRI-TONE® line of vintage and contemporary electric guitar wiring and tube amplifier wire products are sure to meet or exceed OEM performance and appearance, available in large or small quantities and priced right for large manufacturing facilities or for boutique builders.

As an award-winning manufacturer and distributor of aerospace wire and cable products for over 50 years, Whitmor / Wirenetics has expanded the product offerings to include wire and cable products designed specifically for builders of electric guitars, tube (valve) amplifiers and other electric instruments that will meet and exceed manufacturers’ and boutique guitar and amplifier builders’ expectations.

SPACE-LITE® Braid for Lightweight Shielding

You should be looking at our SPACE-LITE® braid using our SPACEALLOY® conductor.


  • Gain up to 50% weight savings over conventional braid depending on the size.
  • RoHS compliant with double the tensile strength of regular copper.
  • Many sizes available off the shelf or can be configured into your custom cable.

There are many options of metalized fibers that have been said can cause FOD issues when used in an outer-space environment. This will not happen with SPACE-LITE® braid.

The carbon nano-tube process is still many years away from a high production solution as we have been involved with several trial materials that just don’t hit the mark for today’s environment.  We have partnered in SBIR’s with light weight composite materials that turn out to be very limited in application and probably not worth the potential weight savings it may bring.

SPACE-LITE® braid is being used today in launch vehicles, satellites and other areas where a dependable lighter weight braid is a benefit.
