A timing drive belt is a transmission belt made from elastomers, having a flat outer surface with a number of teeth on the internal surface, widely used in internal combustion engines to control the valve timing. The belts are generally made from rubber with high tensile fibers, such as Kevlar or fiberglass, running through it. However, rubber's poor resistance to high temperatures has led to the development of timing belts made from highly saturated nitrile (HSN) that deliver significant resistance to high temperatures. Initially, the timing drive belts were designed with trapezoidal teeth, which suffered from high tooth wear rates. This has led to the development of curved teeth, which last longer and run quieter.

The Type-J thermocouple is made of Iron & Constantan (Fe & Cu-Ni) alloys, and can be used in different types of media like inert, oxidizing, reducing and vacuum. The temperature range for this type is -270 to 1200°C. The presence of iron can cause rusting and oxidation problems.

The Type-K thermocouple is made of Chromel (Ni-Cr) and Alumel (Ni-Al) alloys. They are suitable for inert and oxidizing media in the temperature range of -270 to 1350°C.

Type-T thermocouples are made from alloys of Copper & Constantan (Cu- Ni) and have a temperature range of -270 to 400°C. They are suitable for use in inert, oxidizing, reducing and vacuum media.

Teflon hoses are conveying pipes with an inner core made of Teflon and is used for transporting fluids of higher pressure and temperature. Also referred to as pipes or tubing, these hoses are subjected to an extrusion, and possesses a rubber outer cover, uses a stainless steel or bronze wire reinforcing braid as an inner cover. They are light in weight, exhibit inertness towards most chemicals, and are used to convey liquids, gases, and various chemicals. They are available in different lengths, sizes and end-fitting configurations, and are common in aircraft systems, pump connection and petroleum transfer applications.

A tube and wire thermocouple is made of thermocouple wire placed in a metal tube called the sheath probe. Sheath is made of metals like Inconel and stainless steel, fiberglass and mineral insulators. Melting point of the sheath also varies from 1405°C for steel to 1260°C for Hastelloy.

The Type-B thermocouple, which is also called a Noble metal thermocouple (along with type R), consists of 70% Platinum/ 30% Rhodium and 94% Platinum/ 6% Rhodium. It can be used in Inert and Oxidizing media at a temperature of -50 to 1750°C.
