End Face Fully Sealed Rubber Expansion Joints
Company video
A Rubber Expansion Joint with Full Sealing Surface is a specialized
type of flexible
joint designed to accommodate thermal expansion, vibration, and
movement in
piping systems while ensuring a high level of sealing. It is
commonly used in various
industries such as water treatment, HVAC, chemical processing, and
more, where
leakage prevention is crucial.

Key Features of Rubber Expansion Joint with Full Sealing Surface:
1. Full Sealing Surface:
The full sealing surface design refers to the expanded area around
the joint that
provides complete contact with the mating flange. This ensures an
excellent seal
and eliminates potential leakage points, even under high-pressure
conditions. This
type of joint is especially effective in systems where sealing
integrity is critical,
such as in high-pressure pipelines or systems with aggressive
media.
2. Flexibility and Absorption:
Rubber expansion joints with a full sealing surface are capable of
absorbing large
amounts of vibration and thermal expansion. The rubber material
itself is flexible,
allowing the joint to accommodate axial, lateral, and angular
movements without
compromising the system’s integrity.
3. Materials:
These joints are typically made from high-quality synthetic rubber
compounds such
as EPDM (Ethylene Propylene Diene Monomer), NBR (Nitrile Butadiene
Rubber),
or FKM (Fluorocarbon Rubber), depending on the application and the
type of media
the joint will be exposed to.
• EPDM is commonly used for water, air, and steam applications.
• NBR is suitable for oil, fuel, and other hydrocarbon-based
systems.
• FKM is used for aggressive chemicals and high-temperature
environments.
