Duct Flange Gasket por
A closed-cell EPDM rectangular gasket that compresses between mating duct flanges to close air-leak paths around the joint.
- Closed-Cell EPDM
- Four Bolt Holes
- Rectangular Air Opening
- Compressible Cut Edge
Introducción del producto
The gasket is cut from thick black closed-cell EPDM with a central rectangular air opening and four corner bolt holes. Its broad perimeter compresses between mating duct flanges while the cellular edge accommodates minor surface variation.
Características clave
Four holes align with a simple corner-bolted flange pattern.
A broad sealing land distributes compression around the opening.
The resilient cut edge accommodates minor flange irregularity.
Preocupaciones del producto del cliente
Rigid or uneven duct flanges require a compressible interface to prevent leakage around the air opening.
Minor flange waviness leaves leakage paths.Compressible EPDM conforms to local surface variation.
Misaligned holes distort the gasket during assembly.The four-hole pattern is cut to the mating flange dimensions.
Thin seals extrude under bolt pressure.Selected thickness and broad sealing land distribute compression.
Open-cell materials absorb moisture.Closed-cell EPDM limits fluid uptake through the gasket body.
