Bellow for Sigma AL-KO New AK300 Type Coupler

Keep your trailer’s braking system operating flawlessly with this premium replacement Rubber Bellow (Gaiter), specifically designed for AL-KO Sigma and New AK300 type braked couplers.

The bellow is a critical line of defense for your overrun hitch. It completely seals and protects the precision internal drawbar mechanism from harsh road grime, mud, dust, and moisture. Left unprotected, dirt and water can wash away essential grease, leading to premature wear, rust, and potentially dangerous binding or locking of your trailer brakes.

• Premium Protection: Seals out environmental contaminants, ensuring the internal drawbar slides smoothly for reliable overrun braking performance.
• Heavy-Duty Compound: Molded from high-grade, flexible rubber that resists UV cracking, ozone degradation, and automotive greases or oils.
• Exact Fit: Engineered specifically to match the dimensions and lip profile of AL-KO Sigma and AK300 type coupling units for a secure, airtight seal.
• Easy Maintenance: A simple, cost-effective replacement part that prevents expensive wear and tear on your coupler’s internal shafts and dampers.
