    Piston Ring Kit

    The Piston Ring Kit (004 45 N0) restores compression sealing and proper oil control within the cylinders. Replacing it with a Porza-quality set ensures efficient combustion and reduced oil consumption.

    FAQ

    A piston ring kit is a complete set of piston rings designed for one or more pistons in an engine or compressor. It typically includes compression rings and oil control rings required to properly seal the combustion chamber, maintain compression, and regulate oil consumption.

    Key specifications include piston diameter, ring thickness, number of rings per piston, material type, and compatibility with the specific engine or compressor. Piston rings are usually made from cast iron or steel alloys with wear-resistant coatings, designed to withstand high temperatures, pressure, and friction—often exceeding +200°C in engine applications.

    Replacement is necessary when the rings are worn, damaged, or no longer seal properly. Common symptoms include loss of compression, increased oil consumption, reduced performance, or exhaust smoke. Piston ring kits are typically installed during engine or compressor overhaul to restore efficiency.

    Porza offers a fit guarantee option where your vehicle or technical details are checked against product specifications. This ensures the piston ring kit matches the correct dimensions and requirements for your engine or compressor.

    Porza supplies high-quality engine and compressor components with fast delivery across Europe. Customers can order online or choose in-store pickup in the Netherlands, Germany, or Belgium. This ensures quick access to essential maintenance parts for both professional workshops and individual users.

    If you select the fit guarantee, Porza verifies compatibility before shipment. If the product does not fit or meet expectations, it can be returned according to the return policy. This ensures a reliable and risk-free purchasing experience.
