Door and window seal Karcher 2.633-005.0, rubber, black, 280 mm width

The Kärcher door/window seal is a rubber sealing strip in black with a width of 280 mm, designed to improve insulation and moisture protection around doors and windows. Manufactured to fit typical frame edges, this flexible seal reduces drafts, limits water ingress, and contributes to thermal efficiency in residential and light commercial installations.

Advantages

The rubber construction provides durable elasticity and reliable compression recovery, ensuring a tight seal over repeated opening and closing cycles. Its black finish offers a discreet appearance on most frame materials while resisting minor surface wear. The 280 mm width covers larger gaps and helps to reduce sound transmission as well as heat loss. The product is simple to trim and adapt to common installation requirements.

Suitable for

• Sealing external doors to reduce drafts and moisture penetration
• Closing gaps around windows to improve thermal insulation
• Replacing worn or damaged seals in residential doors and windows
• Use in light commercial premises where moderate weatherproofing is required

Key specifications

• Material: rubber
• Color: black
• Width: 280 mm
• Function: sealing for doors and windows, moisture and draft protection
• Form: flexible strip suitable for trimming to length

How to use

Measure the length of the door or window frame where the seal will be installed and trim the rubber strip to the required size with a sharp cutter. Prepare the frame surface by cleaning it from dust, grease and loose particles to ensure good contact. Position the seal along the frame edge so that it compresses slightly when the door or window is closed; secure it according to the frame design (insert into a dedicated groove, attach with adhesive or fasteners as appropriate). Verify uniform compression along the perimeter and make small adjustments if necessary to avoid binding during operation.

Usage recommendations

For best performance, avoid exposing the rubber seal to strong solvents or prolonged direct sunlight. Check the seal periodically for wear or deformation and replace it if compression recovery is reduced or sealing is compromised. When installing on painted or delicate surfaces, test adhesion or fastener placement on a small area first.
