At $20.33, this is the right part when 3\/8\" copper discharge tubing connects to the check valve, which then threads into a 1\/2\" tank bung — stepping up in size while transitioning from compression tube to threaded pipe in one valve body. Rated 500 PSIG and 400 degrees F with a 1\/8\" unloader port.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e CTD3812\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection:\u003c\/strong\u003e 3\/8\" Compression tube fitting\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 $20.33\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\u003eCTD3812 vs. CTB3812\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCTD3812 (this listing):\u003c\/strong\u003e Compression inlet — 3\/8\" copper tubing inserts and is clamped by compression fitting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCTB3812:\u003c\/strong\u003e NPT female inlet — 3\/8\" male NPT fitting threads in from discharge side\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCTD Series Reference\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCTD3838\u003c\/strong\u003e — 3\/8\" comp x 3\/8\" NPT, $20.33\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCTD3812\u003c\/strong\u003e — 3\/8\" comp x 1\/2\" NPT (this listing), $20.33\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCTD1212\u003c\/strong\u003e — 1\/2\" comp x 1\/2\" NPT, $21.18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCTD1234\u003c\/strong\u003e — 1\/2\" comp x 3\/4\" NPT, $29.65\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCTD3434\u003c\/strong\u003e — 3\/4\" comp x 3\/4\" NPT, $29.65\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCTD3410\u003c\/strong\u003e — 3\/4\" comp x 1\" NPT, $46.59\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy Buy From Air Compressor Factory Direct?\u003c\/h3\u003e\n\u003cp\u003eWe stock the full Castair check valve line.
