Another crucial factor in the overall cost of gypsum grid ceilings is installation. The complexity of the installation process can greatly affect labor costs. While some homeowners may choose to install the ceilings themselves, hiring professionals is often advisable to ensure proper installation and adherence to building codes. Professional installation can add $1.00 to $3.00 per square foot to the overall price, depending on the region and the contractor's experience.

The perfect remedy for this is to use oil seal materials that are rated for the temperature of your application. Also, ensure that the elastomer is free from volatile constituents like waxes, plasticizers, etc.

Oil seal characteristics
The block is unlikely to distort except after severe overheating, but check anyway using a steel ruler or similar high-quality straight-edge.
Among the most common causes of oil seal failure are:
These types are made with a metal outer case and a PTFE lip. They are suitable for a wide range of temperatures from -90 °C to +260 °C.These lip seals can also be used for higher pressures of up to 10 bar (special types up to 25 bar) and rotational speeds of up to 40-45 m/s. Certain grades of PTFE are suitable for use in pharmaceutical and food applications. One important point is that PTFE lip seals do require a shaft with a harder, smoother finish.

Fluid side face The front-end face of the seal is called the nose. The nose is made of rubber and forms a gasket seal when compressed on the housing shoulder.
ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).
When there is a need for rebuilding a cylinder and pump instead of building a new one.
