Product Overview
KL116 static seal is a double-acting sealing element produced from thermoplastic polyurethane, providing higher extrusion resistance and longer service life compared to o-rings and other elastomer static seals.
Symmetrical seals are typically centered in the gland and have sealing contact only through the seal lips; therefore, this seal design is less stable during cycles, creating rocking and pumping effects which in turn can create leakage and seal damage. The primary reason for the existence of symmetrical seals is its interchangeability between rod and piston applications; same seal can be used as a rod or piston seal.
For the best sealing performance and durability, we recommend selecting non-symmetrical rod or piston seals depending on your application. These seals have very specific design features that deliver better sealing performance than symmetrical seals do.
Frequently Asked Questions
What are the main benefits of using KL116 static seals?
The KL116 static seal is made from high-grade thermoplastic polyurethane, offering superior extrusion resistance and a longer operational lifespan compared to standard O-rings.
Can this seal withstand high-pressure environments?
Yes, the KL116 is designed for heavy-duty applications and can handle a maximum pressure of up to 600 Bar.
Is the KL116 seal interchangeable with other products?
Absolutely. It is specifically designed to be interchangeable with standard O-rings and O-rings with back-up rings in many industrial applications.
What is the operating temperature range for these PU seals?
These sealing elements perform reliably in temperatures ranging from -35°C up to +110°C.
Where are these seals commonly applied?
They are widely used in construction machinery, cranes, injection moulding machines, and standard industrial hydraulic cylinders.
What is the difference between symmetrical and non-symmetrical seals?
Symmetrical seals allow for interchangeability between rod and piston uses, making inventory easier to manage. However, non-symmetrical seals often provide enhanced sealing performance for specific applications.
