Supported Applications
The Dwyer Series A-4000 consists of Quick Connect Pneumatic Valves designed specifically for air service. These installation fittings provide tubing to male NPT connections, serving as interface components in pneumatic systems where rapid connection and disconnection are required.
Operating Conditions & Performance
The series is rated for a pressure range of -29.5 in Hg (-750 mm Hg) to 150 psi (10 bar). Operating temperature limits are specified as 32 to 140°F (0 to 60°C). The service media is restricted strictly to air; the documentation explicitly states "no other gases or liquids." Wetted materials include polyurethane, polyethylene, and nylon.
Configuration Options
The Series A-4000 offers two primary model families distinguished by connection geometry: standard tubing-to-NPT fittings (A-4002) and variants with an extension (A-4022). The series supports multiple tubing outer diameters paired with NPT thread sizes.
Model A-4002 Configurations
The A-4002 family provides direct connections without extensions. Available combinations of Tubing O.D. and Male NPT include:
- A-4002-0: 5/32" x 1/8"
- A-4002-1: 5/32" x 1/4"
- A-4002-2: 1/4" x 1/8"
- A-4002-3: 1/4" x 1/4"
- A-4002-4: 5/16" x 1/8"
- A-4002-5: 5/16" x 1/4"
- A-4002-6: 3/8" x 1/8"
- A-4002-7: 3/8" x 1/4"
Model A-4022 Configurations with Extension
The A-4022 family includes an extension feature. Documented configurations include:
- A-4022-2: 1/4" x 1/8" with Extension
- A-4022-4: 5/16" x 1/8" with Extension
Overall dimensions for the A-4002 are listed as 2-5/16 [58.7] x 1-9/16 [39.8] x 11/16 [17.4]. The overall length for the A-4022 with extension is 2-13/16 [71.4]. Weights are specified as 1 oz (28 g) for the A-4002 and 1.3 oz (36 g) for the A-4022.
Key Product Differences
The primary distinction within the series is the presence of an extension on the A-4022 models versus the standard configuration of the A-4002. Both families utilize polyurethane, polyethylene, and nylon wetted materials and share identical pressure and temperature limits. Metric and alternate connection sizes are not listed in the standard model chart; users must contact the factory for these options.
