At $21.18, it's used where the compressor head discharge port is 3\/8\" NPT but the tank connection is 1\/2\" NPT, bridging these two sizes in one valve body without additional reducers. Rated to 500 PSIG and 400 degrees F with a 1\/8\" side port for unloader connection.\u003c\/p\u003e\n\n\u003ch3\u003eWhen You Need the CTB3812\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCompressor head has a 3\/8\" NPT male discharge port (common on smaller portable and light commercial compressor heads)\u003c\/li\u003e\n\u003cli\u003eTank has a 1\/2\" NPT female bung\u003c\/li\u003e\n\u003cli\u003eNeed to bridge the two sizes in one valve body without reducers or adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e CTB3812\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection:\u003c\/strong\u003e 3\/8\" NPT Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Connection:\u003c\/strong\u003e 1\/2\" NPT Male\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating:\u003c\/strong\u003e 500 PSIG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating:\u003c\/strong\u003e 400 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnloader Port:\u003c\/strong\u003e 1\/8\" side port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrice:\u003c\/strong\u003e $21.18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Castair (Spicer, Minnesota)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompanion Compression Inlet Version\u003c\/h3\u003e\n\u003cp\u003eThe CTD3812 (3\/8\" compression tube fitting inlet \/ 1\/2\" NPT outlet, $20.33) performs the same bridging function with copper tubing inlet rather than a threaded NPT connection.
