Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
EPDM Diaphragm for Valves & Fluid Control
High-Performance EPDM Diaphragm with Chemical Resistance, Elasticity & Temperature Tolerance
Crafted from high-quality EPDM rubber, this diaphragm excels in industrial valve sealing and fluid control. It delivers core advantages: strong resistance to acids, alkalis, and chemicals, ensuring no leakage; excellent elasticity for quick shape recovery and long-term tight sealing; and wide temperature tolerance, working stably in harsh hot/cold conditions.
Designed for precision, it fits seamlessly into valves, filling equipment, and fluid pipelines, guaranteeing reliable operation. Its durability reduces frequent replacements, cutting maintenance costs. A cost-effective choice, it meets diverse industrial needs, empowering smooth, efficient workflows—ideal for those seeking consistent, high-performance fluid system components.

1. Product Advantages
Crafted from premium EPDM rubber, Forever Seals’ diaphragm stands out with 4 core strengths:
Superior Durability: Resists acids, alkalis, and industrial chemicals, avoiding degradation; excellent aging resistance ensures 2x longer service life than ordinary rubber diaphragms.
Reliable Sealing: Outstanding elasticity enables instant shape recovery after pressure, maintaining tight sealing and zero fluid leakage.
Wide Temperature Adaptability: Works stably in -40°C to 150°C (-40°F to 302°F), suitable for harsh hot/cold industrial environments.
Cost-Efficiency: Reduces 30% maintenance frequency and replacement costs, balancing high performance with budget-friendliness.
2. Working Principle
This EPDM diaphragm acts as a flexible barrier in fluid systems. When pressure is applied (e.g., from valve operation), it deforms to control fluid flow or isolate media; once pressure eases, its elasticity drives it back to the original shape, restoring sealing. This “deformation-recovery” cycle ensures precise fluid on/off control and prevents cross-contamination of media, critical for stable system operation.
3. Product Details
Material Quality: 100% high-purity EPDM rubber, compliant with industrial safety standards (RoHS, FDA for food-contact scenarios).
Precision Design: Molded with CNC technology, thickness tolerance ≤ 0.1mm; edge smoothness ensures perfect fit with valves (compatible with Burkert and other major brands).
Structural Feature: Reinforced inner layer enhances tear resistance, avoiding breakage under high pressure.
4. Application Range
Ideal for industries and equipment requiring reliable sealing and fluid control:
Valves: Diaphragm valves, control valves, and check valves in chemical, water treatment, and oil & gas sectors.
Filling Equipment: Beverage, pharmaceutical, and cosmetic (filling valves, flow-limiting valves).
Fluid Systems: Pipeline systems for corrosive media (acids, alkalis) and high/low-temperature fluids.
5. FAQ
Q1: What is the service life of this EPDM diaphragm?
A1: Under normal industrial conditions, it lasts 12–24 months (varies by application environment).
Q2: Is it compatible with food-grade fluids?
A2: Yes—our EPDM material meets FDA standards, suitable for food and beverage processing.
Q3: Can custom sizes be provided?
A3: Absolutely—Forever Seals offers custom solutions based on your equipment drawings and requirements.
