Diatax is an industry-leading manufacturer of high-performance elastomeric diaphragms engineered for dynamic fluid regulation and critical sealing. Driven by our advanced technical textile knife-over-roll coating, precision calendering, and high-tonnage molding capabilities, we develop both standard replacement membranes and highly complex custom profiles. Specializing in structural capabilities ranging from 5mm to 1250 mm, our elastomeric seals operate as impermeable dividing walls separating distinct mechanical chambers, effectively blocking cross-contamination while flawlessly transferring pressure differentials.
To conquer strict pressure, chemical, and environmental tolerances, Diatax engineers a diverse range of structural constructions tailored exclusively to your operational specifications.
| Construction Type | Overview & Ideal Application |
|---|---|
| Fabric-Reinforced | High-tensile textiles encapsulated in rubber for extreme burst resistance and flexibility. Ideal for high-pressure actuators and air brakes. |
| Homogeneous | Pure elastomer without fabric reinforcement, providing instantaneous sensitivity. Ideal for low-pressure gas regulators. |
| PTFE-Lined | Chemically inert PTFE bonded to rubber for absolute chemical immunity. Ideal for sanitary valves and aggressive solvents. |
| Insert Molded | Metallic hardware bonded directly into the rubber to eliminate assembly steps. Ideal for AODD pumps and control valves. |
| Molded Die Cut | Precision die or laser-cut seals manufactured from our in-house rubber sheets, available with single, 2, 3, or 4-ply fabric inserts. Ideal for custom gaskets and flat flange sealing. |
At Diatax, we manufacture an exclusive line of 0.2mm ultra-thin diaphragms engineered specifically for ultra-critical applications. Through a highly specialized manufacturing process, we apply a precision double-sided rubber coating over a micro-thin fabric reinforcement layer. This results in a highly sensitive, durable membrane that serves as the gold standard for autogas reducers and highly calibrated gas meters. To further optimize OEM assembly lines and enhance sealing efficiency, Diatax manufactures these thin diaphragms with pre-attached paper gaskets specifically designed for autogas reducers, ensuring an instant, leak-proof seal upon installation.
At Diatax, we manufacture advanced multi-ply diaphragm sheets featuring 2, 3, and 4 fabric inserts designed exclusively for heavy-duty flat cut diaphragms. These highly reinforced sheets are engineered for extreme-demand applications, such as high-capacity autogas reducers and pneumatic systems requiring unparalleled burst strength. Utilizing our proprietary compounding and calendering technology, every individual fabric ply is deeply penetrated and vulcanized to guarantee extreme pressure resistance and superior tear strength. This specialized manufacturing protocol guarantees zero peeling or delamination between the structural layers, providing a fail-safe dynamic seal under the most severe mechanical stress.
The foundation of a reliable diaphragm is advanced raw material compounding and precision engineering. Diatax processes premium elastomeric compounds to meet the most demanding industrial specifications.

Rolling diaphragms are specialized dynamic seals crafted for applications requiring frictionless operation between a moving piston and a stationary cylinder. As the hardware actuates, a molded convolution smoothly unwinds along the cylinder wall, entirely eliminating sliding friction, mechanical wear, and spring resistance. This results in highly accurate stroke positioning and an extended cycle life.
Diatax manufactures multiple flange profiles to suit your specific hardware requirements:
At Diatax, we engineer convoluted diaphragms containing deeply molded U-shaped or V-shaped bends, enabling significantly larger displacement and enhanced sensitivity compared to standard flat profiles. They deliver critical responsiveness in low-pressure pneumatic controllers, fluid actuators, and highly sensitive regulators.
Serving as the most cost-effective solution for dynamic sealing, Diatax manufactures flat diaphragms tailored for systems with minimal displacement and high-frequency actuation. Backed by our advanced in-house calendering facility, we manufacture fabric-reinforced calendered sheets in precise continuous thicknesses, including 0.2mm, 0.3mm, 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 2mm, and 2.5mm. Precision manufacturing of these ultra-thin reinforced sheets is vital for achieving optimal flex life and sensitivity in industrial applications. For absolute burst strength in high-stress applications, we also supply custom multi-ply sheet constructions featuring multiple integrated textile layers.
We design, compound, and manufacture our DTX-Series diaphragms based strictly on their end-use environment, ensuring optimal material compatibility and lifecycle performance.
At Diatax, our valve membranes are formulated to maximize cycle endurance and provide leak-proof isolation in flow control systems. View All Valve Diaphragms
Air-Operated Double Diaphragm (AODD) pumps are the backbone of fluid transfer in harsh industrial settings. Because even the smallest membrane rupture compromises the entire pumping system, absolute reliability is mandatory. Diatax manufactures ultra-resilient pump diaphragms built to endure continuous, violent flexing against caustic chemicals, heavy slurries, and aggressive industrial solvents. We offer more than 40 different models of PTFE and rubber diaphragms, along with complete, ready-to-use repair kits for all major pump brands. View AODD Pump Diaphragms
This is a highly critical sector, as gas meter diaphragms typically measure just 0.2mm in total thickness, including both the rubber coating and the structural fabric reinforcement. Maintaining the exact convolution depth and long-term elasticity is the ultimate factor for accurate volumetric billing. At Diatax, we achieve this using our proprietary technology to manufacture ultra-thin diaphragms from specialized EN549-rated elastomeric compounds developed exclusively for gas meter applications. We manufacture precision diaphragms for standard gas meter models including G1.6, G2.4, and G4, as well as volume-based models like 0.9d and 1.2d. We proudly supply these engineered components to gas meter manufacturers globally, ensuring absolute dimensional stability and resistance to degradation from natural gas over decades of continuous field use.

Commercial transport and heavy rail transit depend on fail-safe pneumatic braking systems. Diatax manufactures premium fabric-reinforced air brake diaphragms molded for maximum burst strength, tear resistance, and reliable actuation across extreme environmental temperature swings. We manufacture membranes in all standard commercial sizes, including T16, T20, T24, T30, and T36, as well as specialized "L" models to meet exact pneumatic specifications. View Air Brake Diaphragms
At Diatax, we manufacture specialized automotive reducer diaphragms engineered specifically for the alternative fuel industry to regulate high-pressure natural gas and liquid petroleum down to safe injection levels. We utilize proprietary NBR and engineered elastomers highly resistant to gas permeation, volumetric swelling, and thermal degradation.
