In metal fabrication, 4-inch Tek screws excel in joining steel, aluminum, or other metal components. They are especially useful in the construction of steel buildings, where they provide robust connections for roofing, siding, and framing. Their self-tapping feature reduces installation time and effort, making them a favorite among contractors and DIY enthusiasts alike Their self-tapping feature reduces installation time and effort, making them a favorite among contractors and DIY enthusiasts alike
- A PU oil seal is essentially a barrier that seals off mechanical parts, particularly those in contact with oils or other lubricants. The 'PU' in the term refers to polyurethane, a versatile material known for its high resilience, excellent abrasion resistance, and ability to withstand extreme temperatures. This makes it ideal for use in harsh operating conditions where conventional rubber seals may fail.

The benefits of Viton include:
- A double oil seal, also known as a tandem seal or a dual seal, consists of two sealing elements placed in series. This design offers a two-layered defense against contamination ingress and fluid egress, thereby enhancing the overall sealing performance. The primary seal acts as the first line of defense, while the secondary seal serves as a backup, providing redundancy in case the primary seal fails.

There is a British Standard laid down for the control of synthetic rubbers. BS 3574 (1989) helps to determine shelf life – for instance, Nitrile (NBR) and Polyacrylic (ACM) are Group ‘B’ rubbers and have a 7-year life, whilst Silicone (VMQ) and Fluoroelastomers (Viton®) are Group ‘C’ rubbers and have a 10-year shelf life. PTFE and Leather do not come into this category but like the others should be kept in the original packing for as long as possible away from direct light, dust, and humidity. Ozone, which can also be produced by battery-driven forklift trucks has a very bad effect on synthetic rubbers. Finally, protect the sealing lip – DO NOT hang the seals on nails, wire etc.

Neoprene foam gaskets are an essential component in various industrial and commercial applications. These gaskets are made from a type of synthetic rubber known as neoprene, which is valued for its excellent resistance to chemicals, oils, and extreme temperatures. Neoprene foam gaskets have unique properties that make them ideal for sealing and insulation purposes in a wide range of industries.
The head gasket and valve cover gasket are critical components in the engine's sealing system. The head gasket seals the cylinder head to the engine block, while the valve cover gasket seals the valve cover to the cylinder head. Both gaskets play pivotal roles in maintaining the integrity and functionality of the engine, preventing oil leaks and ensuring the proper sealing of the combustion chamber.

Oil seals keep contaminants separate from the lubricants that keep rotating shafts and precision bearings in good working order. Oil seals are also known as rotary shaft seals, lip seals, and shaft seals.
