DETAILS
Model GP402 is a brass two-stage regulator with neoprene diaphragms for general-purpose laboratory applications. The GP402 maintains a constant delivery pressure from full to near empty cylinder conditions. The GP402 is not recommended for high purity applications that may be sensitive to contamination due to elastomeric components. This model is suitable for non-corrosive industrial grade gases, purging, pressure testing and gas shielding.
Features
- Neoprene diaphragms for greater sensitivity
- One-piece encapsulated seat design with 10 micron sintered internal filter to protect the PTFE Teflon® seat from particulate contamination
- Equipped with tamper-proof, self-reseating internal relief valve
- Electroless nickel-plated brass body, painted die cast bonnet and brass fittings
- 2 in. Brass dual scale easy-to-read gauges (psi/kPa)
- Constant delivery pressure from full to near empty cylinder conditions
- Maximum inlet pressure 3000 PSIG
- Conforms to CGA E-4 standard for gas pressure regulators
