O-ring FKM 42 B Press Solar PH4992 0420400

Sealing reliability in copper installations

The FKM 42 B Press Solar O-ring is a key sealing element, dedicated to the Conex B Press Solar press fitting systems. Made of high-quality fluororubber (FKM), it ensures reliable and durable connections in copper installations, especially where resistance to high temperatures and aggressive media is required. Its precise dimensions and material guarantee tightness and safety of use.

Construction and application

This round sealing ring, with an inner diameter of 40.2 mm and a thickness of 4.05 mm, is an integral part of the Conex B Press Solar press fittings. Its task is to ensure the tightness of the connection between the elements of the copper installation after the crimping process. FKM (Fluoroelastomer) is a material characterized by exceptional chemical and thermal resistance – ideal for use in heating, domestic water and air conditioning systems. Thanks to this, the O-ring retains its sealing properties even in difficult operating conditions.

Key features and benefits

• High chemical resistance: FKM material is resistant to the action of many chemicals, which ensures long-term tightness of the installation.
• Temperature resistance: The O-ring retains its properties over a wide temperature range, which is important in heating and air conditioning systems.
• Precise dimensions: Ensure a perfect fit for Conex B Press Solar fittings, guaranteeing a tight connection.
• PI (Press Indicator) system: The green color of the FKM elastomer indicates the correctness of the fitting crimping – “uncrimped, not tight”. This is a simple quality control of the connection execution for the installer.
• Durability and reliability: Fluororubber is characterized by high resistance to aging and wear, which translates into a long service life of the seal.
• Compatibility: Designed for use with copper pipes in accordance with PN-EN 1057 and stainless steel pipes in accordance with PN-EN 10312.

Thanks to these features, the FKM 42 B Press Solar O-ring guarantees safe and trouble-free operation of the installation for many years. It is an essential element for both professional installers and end-users who value quality and reliability of their heating or water system in their home.
