The BlowTie is used to release excess pressure on a pressurized fermenter or from a receiving keg during pressure transfers. This diaphragm spunding valve is much more accurate than the spring and poppet style, and works much better at lower pressures.\n\nPressure Fermentation\n\nPressure fermentation is becoming more and more popular at the homebrew level, but in order to do it safely and accurately, you need a way to release excess pressure. You'll pressurize your vessel to your desired psi, but once fermentation begins and those hungry, active yeast start creating CO2, the pressure inside the vessel will increase. Attach a spunding valve and set it to your desired pressure, and it will blow off when the pressure gets to high and close up again when it's back to your desired psi.\n\nPressure Transfers\n\nEven if you don't have a pressurizable fermenter, you may have done pressure transfers from keg to keg during filtering or after fining. During pressure transfers, it's a good idea to have a bit of head pressure in the receiving keg, especially if you're transferring beer that is already carbonated. Having a spunding valve in place will allow you to consistently control the head pressure and give you more consistent results, without losing carbonation in the process.\n\nDiaphragm vs. Poppet\n\nWith the poppet style spunding valve, a spring pushes against a poppet to keep the valve closed. When the poppet lifts up to open, the surface area the gas pushes against becomes larger, and the spring has to work harder to push the poppet down and reseal the valve. This can lead to more gas being released than intended, and the remaining pressure in your vessel may be at a lower psi than your spunding valve's set psi.\n\nInstead of a poppet, the spring inside the BlowTie pushes against a diaphragm, which has an immensely larger surface area. This means the surface area that the gas pushes against while the diaphragm is closed is significantly closer to the surface area it pushes against when the diaphragm is open. This leads to higher accuracy, and the remaining pressure after excess gas is released will be much closer to your set blow off pressure.\n\nKit Includes:\n\nBlowTie\n\nPressure Gauge (0-40 psi)\n\nBall Lock Disconnect\n\nDuotight Tee \u0026amp; Flared Duotight Fitting\n\n2x Lengths of EVABarrier 8mm OD Tubing\n\n\u003ca href=\"https:\/\/northtexashomebrew.com\/product-category\/draft-keg\/\"\u003eSee all our Draft and Keg options here. \u003c\/a\u003e","brand":"Brewmaster","offers":[{"title":"built-in","offer_id":47280915382460,"sku":"fe963","price":32.99,"currency_code":"USD","in_stock":true},{"title":"triple scale","offer_id":47280915415228,"sku":"fe961","price":38.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/7370\/6172\/files\/blowtie2spunding963.png?v=1786816600"},{"product_id":"plastic-pressure-kit-for-fermzilla","title":"Plastic Pressure Kit for Fermzilla","description":"With the FermZilla Pressure Kit you can ferment under pressure, carbonate, and serve without ever needing to move your beer out of the fermenter. The kit inlcudes two plastic female threaded ball lock fittings with barbs, which thread onto the existing openings atop the FermZilla's lid. For the beverage out, you'll have a silicone dip tube with stainless steel float, allowing you to always draw from the clearest beer at the top of the tank.?Pick up the Pressure Kit and turn your FermZilla into a true unitank!\n\nThe silicone dip tube is 31\" long. It will work perfectly as is for the \u003ca href=\"https:\/\/northtexashomebrew.com\/product\/fermzilla-tri-conical-fermenter-gen-3-2-3-tri-clamp-collection-container-55l-13-2gal\/\"\u003e55L FermZilla\u003c\/a\u003e. For the 27L model we recommend cutting the dip tube shorter to remove unwanted slack.\n\nWith the optional \u003ca href=\"https:\/\/northtexashomebrew.com\/product\/floating-dip-tube-filter-attachment\/\"\u003eFloating Dip Tube Filter\u003c\/a\u003e, you can prevent hop material and other solids from ever entering the dip tube. Especially handy when you're pulling samples mid-fermentation!\n\nFermenting Under Pressure:\n\nThe pressure kit allows for fermenting under pressure, which will reduce esters and fusel alcohol production. This means you can ferment at warmer temperatures than you normally would, even making lagers at room temperature. Most commerical beer is fermented under pressure simply due to the size of commercial tanks and the pressure that is created by the column of beer. It is one of the distinct differences between homebrewing and brewing on a commercial scale. The FermZilla's lid already comes with a built-in pressure relief valve that will blow at 35 psi; the pressure kit simply allows you to add CO2 through the ball lock fitting. We strongly recommend that you also purchase an adjustable pressure relief valve, or spunding valve, which allows you to set a lower pressure. It's always a good idea to have two relief valves on the FermZilla anytime the unit is under pressure.\n\nCarbonating, Transferring, and Serving:\n\nWhen you are fermenting under pressure the beer is already carbonated when you are done fermenting. You can control the level of carbonation by using a spunding valve. This means you can eliminate kegging and serve directly from the fermenter. We love this idea but there will probably still be times that you want to keg. Attach a beer line from the FermZilla's bev out to your keg and enjoy the easiest kegging experience ever.? You can also choose to send carbonated beer through a beer filter on the way to your keg.? When applying pressure with a CO2 tank also make sure that you have a functional relief valve on your CO2 regulator.\n\nEliminate Oxidation:\n\nSince the beer always has a CO2 blanket through fermentation and during any transfers out, oxidation is eliminated. When you cold crash you won't be sucking air back in through an airlock.","brand":"Brewmaster","offers":[{"title":"Default Title","offer_id":47280931668156,"sku":"fe143","price":24.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/7370\/6172\/files\/34909.png?v=1786816961"},{"product_id":"duotight-blowtie-2-diaphragm-spunding-valve","title":"Duotight BlowTie 2 Diaphragm Spunding Valve","description":"Automatically release pressure inside your fermenter during pressure fermentations\n\nRegulate beer flow during pressurized transfers from fermenter to keg\n\nBuilt-in pressure gauge for easy reference when adjusting the spunding valve\n\nPressure gauge is interchangeable—swap to different \u003ca href=\"https:\/\/northtexashomebrew.com\/?s=mini+pressure+gauge\u0026amp;post_type=product\u0026amp;type_aws=true\"\u003epressure ranges\u003c\/a\u003e that better suit your application\n\nDiaphragm spunding valves offer higher accuracy compared to spring \u0026amp; poppet spunding valves\n\n8 mm Duotight inlet\/outlet for use with 8 mm OD \u003ca href=\"https:\/\/northtexashomebrew.com\/?s=evabarrier\u0026amp;post_type=product\u0026amp;type_aws=true\"\u003eEVABarrier\u003c\/a\u003e tubing or 8 mm \u003ca href=\"https:\/\/northtexashomebrew.com\/product\/duotight-rigid-plastic-joiner-8mm\/\"\u003eRigid Joiners\u003c\/a\u003e\n\nThe Blow Tie Spunding Valve is used to release excess pressure on a pressurized fermenter or from a receiving keg during pressure transfers.

Dialing in your desired pressure is even easier with the BlowTie 2, thanks to the integrated pressure gauge. Simply start with the adjustment knob fully closed, then slowly open it until the gauge reading matches your desired pressure setting.\n\nSpecifications:\n\nMade from food grade acetal\n\nStainless screws\n\nEasily disassembles for cleaning\n\n8mm (5\/16\") Duotight fittings at both ends\n\nInterchangeable pressure gauge\n\nGauge reads from 0-15 psi\n\nWARNING: Do not exceed gauge pressure.
