2. Product Description 
German Merkel® Stircomatic SRC Conformal Flange Seal (40-48-2.4/3)
The Merkel Stircomatic SRC is a premium static profile seal specially designed with dual cutting-edge sealing lips on its front faces. Built as a high-performance alternative to traditional O-rings and back-up ring combinations, this polyurethane flange seal delivers outstanding stress distribution and reliable seating even under heavy, pulsating pressure peaks.
Manufactured from Freudenberg’s proprietary 95 AU V142 polyurethane, the SRC seal exhibits superior resistance to gap extrusion, mechanical wear, and fluid deformation. It is widely used in high-pressure hydraulic motors, valve manifolds, marine winches, and heavy-duty industrial machinery.
3. Key Technical Features & Benefits 
Feature Technical Advantage  Customer Benefit 
Dual Cutting-Edge Profile Advanced face-sealing geometry with optimal contact stress. Ensures zero leakage under severe pressure fluctuations.
95 AU Polyurethane High hardness, low compression set, and extreme tear strength. Significantly longer service life compared to standard NBR O-rings.
Anti-Extrusion Strength High structural stability resisting extrusion into sealing gaps. Safely operates under high pressure up to 80 MPa (800 bar).
Direct O-Ring Drop-in Designed to fit standard axial O-ring installation spaces. Easy retrofit and maintenance without machining custom housings.
