FAQ
LPG/CNG diaphragms are specifically engineered with gas-resistant elastomers that resist swelling and degradation from hydrocarbon exposure. They feature ultra-thin construction (0.20mm) with fabric reinforcement for high sensitivity while maintaining durability—properties standard diaphragms lack.
Fabric reinforcement provides tensile strength and dimensional stability essential for millions of actuation cycles. It prevents tearing and permanent deformation while allowing thin rubber to remain flexible enough to respond to pressure changes as low as 0.1 kg/cm². Without reinforcement, thin diaphragms would fail prematurely.
These diaphragms are made from gas-resistant elastomers like Nitrile (NBR), Hydrogenated Nitrile (HNBR), and Epichlorohydrin (ECO), combined with reinforcement fabrics such as Nylon or Polyester. The choice depends on factors like LPG/CNG compatibility, temperature resistance (-40°C to +120°C), and required cycle life.
We manufacture diaphragms compatible with most major brands including Lovato, BRC, Tomasetto, Landi Renzo, and OEM regulators (Bajaj, Piaggio, TVS). For specific compatibility, provide regulator model or sample. We can also develop custom diaphragms for unique specifications.
Every diaphragm undergoes 100% individual leak testing using helium or pressure decay methods, plus visual and dimensional inspection. Batch samples undergo pressure cycling (5 million cycles), chemical resistance testing in LPG/CNG, temperature cycling, and tensile strength verification.
Yes, our LPG/CNG diaphragms comply with AIS-026 (Indian automotive LPG/CNG standards) and are ECE R110 compatible. We maintain comprehensive quality documentation and material certifications required by OEMs and regulatory bodies.
Standard designs: 100 pieces minimum. Custom designs requiring new tooling: 1,000-5,000 pieces depending on complexity. Prototype quantities (25-50 pieces) available for testing and validation at reasonable pricing.
We offer OEM-quality with zero-failure track record, 100% leak testing, local manufacturing (no import delays/duties), competitive pricing, technical support, and proven reliability with 3+ million units in service. Total cost of ownership is significantly lower than imports.
