• Wear Guides Precision bearing and wear ring solutions including molded, precision cut, and step cut designs for protecting cylinder bores from rod scoring.
• Back Up Rings Anti-extrusion devices in standard and contoured designs for protecting seals from extrusion into clearances under high pressure conditions.
• Custom Molded Rubber Custom rubber molding services using compression, transfer, and injection molding technologies with custom compounding capabilities for unique material requirements.
• Machined Plastics / Engineered Plastics Precision machined plastic components including rotary seals, reciprocating seals, and face seals in PTFE, nylon, and other engineered thermoplastics.
• Spring Energized Seals PTFE or polymer seals energized by stainless steel springs for demanding applications requiring low friction, chemical resistance, and wide temperature ranges.
• PTFE Seals Polytetrafluoroethylene-based sealing solutions offering exceptional chemical resistance, wide temperature range, and low friction characteristics.
• O-Ring Kits Pre-assembled compartment kits (12 and 36 compartment options) containing popular O-Ring sizes for maintenance and repair applications.
• Seal Kits Complete sealing solution kits including piston seals, rod seals, wipers, wear guides, and O-Rings grouped for specific hydraulic cylinder applications.
• Engineering Services Design assistance, material selection, CAD services, and reverse engineering services provided to industrial OEM customers to support sealing solution selection and development.
• Warehouse & Logistics Services (VMI / EDI) Vendor Managed Inventory (VMI), Electronic Data Interchange (EDI), custom packaging, kitting, and just-in-time delivery services for industrial customers requiring dedicated inventory levels.
• F-7041 Viton B Compound for Methanol Blended Fuels F-7041 Viton B compound specifically designed for methanol-blended fuel applications, offering improved methanol resistance over Viton A with more competitive pricing than Viton GF or GFLT, continuing the company's line of premium UL-listed genuine Viton compounds.
• N-7003 HNBR Compound for HFO-1234yf Refrigerant Premium HNBR compound N-7003 evaluated and confirmed compatible with HFO-1234yf eco-friendly automotive refrigerant, tested in both R134a/PAG oil and HFO-1234yf/PAG oil mixtures, designed for automotive air conditioning seal applications.
• Tecnoflon VPL FKM Compounds (F-7067, F-7068) Two new Tecnoflon VPL FKM compounds (F-7067 at 75 durometer/TR10 -40C and F-7068 at 75 durometer/TR10 -30C) offering exceptional low temperature flexibility and improved chemical resistance for demanding automotive and industrial sealing applications.
• N-7575 75 Durometer Nitrile Compound N-7575 is a 75 durometer NBR compound featuring numerous Underwriters Laboratories recognitions under UL Standard No. 157, based on N-7079 material with additional UL end use recognitions facilitating substitution for competitor compounds in fuel and gas applications.
