- 2. HVAC Systems In HVAC systems, molded gaskets are used to seal ductwork, air handlers, and other components to prevent air leaks and maintain optimal indoor air quality.

- The science behind skeleton oil sealing lies in the careful selection of materials and the precision manufacturing of the seals. The seal must be able to withstand extreme temperatures, chemical exposure, and physical stress without degrading or losing its effectiveness. Advanced polymers and elastomers are commonly used for this purpose, as they offer excellent resistance to wear and tear while maintaining their elasticity over time.
The spring supplements the tightening force (i.e., the lip radial load) to ensure enhanced sealing performance and tight contact between the shaft and the sealing edge.The spring also prevents the deterioration of main lip sealing performance caused by high heat or other such factors.

How do oil seals work?
In engine applications, square rubber gaskets are used to seal various components such as valve covers, oil pans, and intake manifolds. These gaskets help prevent oil and fuel leaks, ensuring the engine operates smoothly and efficiently.

In this blog, we attempt to highlight what are Oil Seals and the various Rotary Shaft Seals including Mechanical Face Seals, Water Pump Seals, Gland Packings, and V-Seals that are readily available.
Start the engine and check for oil leaks round the sump flange. Stop the engine and tighten the mountings.


One of the main principles of power transmission is consistent lubrication. Shaft seals play a hugely important role in this. Imagine a situation involving a shaft-mount reducer – electric motor prime mover, driven by belts, motion controlled by a torque arm – with an improperly seated seal. A blown-out input shaft seal is a nightmare situation, necessitating an entire breakdown and reassembly, not to mention re-aligning and re-tensioning the belts.
How are they used?
Like any element of the engine, oil seals are subject to wear. Over time they can lead to possible leaks of lubricating liquid.
6 GUIDELINES TO FOLLOW WHEN CHOOSING AN OIL SEAL
These are comparable to type R and RST, except the outer case does not have a metal reinforcement ring. To compensate, the outside is not made of normal rubber, but a hard, heavy-duty rubber fabric. The advantage is that these types can be made in a split version. They are almost always produced to order, and made of NBR or FKM.
