High - Quality Valve Rubber Seals
Premium Sealing Components for Petroleum Equipment
These high-quality valve rubber seals are indispensable core components for petroleum equipment. Expertly crafted from premium polyurethane—a material engineered by adjusting the ratio of crystalline hard segments to non-crystalline soft segments for optimized mechanical performance—they deliver exceptional oil resistance, corrosion resistance, and wear resistance. Capable of withstanding high pressures (up to 40MPa), these seals function as critical inlet and outlet valves for pumps, ensuring reliable sealing in drilling mud pump valve seat operations and cementing truck valve seat applications. They are widely used in oilfield equipment such as fracturing trucks, well-washing trucks, cementing vehicles, and plunger pumps. Beyond preventing leaks, they extend the service life of valve bodies and seats, avoid costly equipment box damage, and reduce safety risks—making them a cost-effective, high-reliability choice for maintaining smooth, efficient oilfield operations.

1. Product Advantages
Forever Seals valve rubber seals stand out in the petroleum industry with four core advantages:
Exceptional Durability: Crafted from premium polyurethane (custom-engineered by balancing crystalline hard segments and non-crystalline soft segments), they resist oil, corrosion, and wear—extending service life even in harsh downhole conditions.
High Pressure Resistance: Rated to withstand up to 40MPa of pressure, ensuring leak-free performance during high-intensity operations like fracturing and cementing.
Equipment Protection: Prevents premature wear of valve bodies and seats, avoids costly damage to equipment casings, and reduces the risk of safety incidents (e.g., pressure leaks).
Cost-Effectiveness: Minimizes downtime for replacements and repairs, lowering overall operational costs for oilfield projects.
2. Working Principle
As critical sealing components for petroleum pumps, Forever Seals valve rubber seals operate on a simple yet reliable mechanism:
When the pump’s plunger moves upward, negative pressure is created inside the pump cylinder. This pulls the valve rubber seal open, allowing drilling mud, cement, or other fluids to enter (inlet function).
When the plunger moves downward, positive pressure builds, forcing the valve rubber seal to press tightly against the valve seat—sealing the cylinder and pushing fluids outward (outlet function).
The polyurethane material’s elasticity ensures a tight seal with every cycle, preventing fluid backflow and maintaining consistent pump efficiency.
3. Product Details
Material: High-grade polyurethane (adjustable hard/soft segment ratio for tailored mechanical performance).
Pressure Rating: Up to 40MPa (suitable for medium to high-pressure oilfield operations).
Dimensions: Customizable to fit standard and non-standard valve seats (e.g., for mud pumps, plunger pumps, and cementing trucks).
Surface Finish: Smooth, burr-free design to ensure seamless contact with valve seats and reduce friction.
Temperature Resistance: -20°C to 80°C (stable performance in extreme oilfield temperature fluctuations).
4. Application Range
Forever Seals valve rubber seals are widely used in oilfield equipment and operations, including:
Equipment Types: Fracturing trucks, well-washing trucks, cementing vehicles, drilling mud pumps, and plunger pumps.
Operational Scenarios: Drilling mud circulation, well cementing, reservoir fracturing, and well cleaning.
Industry Segments: Onshore/offshore oil and gas exploration, shale gas development, and oilfield maintenance.
5. FAQ (Frequently Asked Questions)
Q1: How long do Forever Seals valve rubber seals typically last?
A1: Service life depends on usage conditions (e.g., fluid type, pressure, and temperature). Under standard oilfield operations, they last 3–6 months—20% longer than average industry seals.
Q2: Can these seals be customized for non-standard valve sizes?
A2: Yes. We offer custom dimensions based on your equipment’s technical drawings, with a lead time of 5–7 business days for small-batch orders.
Q3: Are they compatible with all types of drilling fluids?
A3: They are compatible with most common fluids (water-based mud, oil-based mud, and cement slurries). For highly corrosive fluids (e.g., acid-based cleaners), we can provide a specialized corrosion-resistant polyurethane variant.
Q4: What is the warranty policy for Forever Seals products?
A4: We offer a 30-day warranty against material defects. If seals fail due to manufacturing issues within 30 days of delivery, we provide free replacements.
