PET plastic bottles are readily available and inexpensive. The standard thread for PET bottles for carbonated beverages between 0-3L in size is the PCO 1881 thread. This thread type suits our carbonation caps that you can buy in plastic here or stainless steel.
Historically you would only be able to place a black or grey ball lock disconnect onto these fittings one at a time. This tee piece now enables you to attach both a liquid and gas disconnect to the bottle at the same time so you can essentially use a common PET bottle as a keg.
Note: The PET soft drink bottle and dip tube are not included.

Looking for high quaility push in fittings that will seal tight? Duotight are the push in fitting with superior sealing capacity due to the double o-ring sealing design.
Why use Double O-rings?
The secret to the Duotight sealing performance is not just the fact that it uses high quality EPDM o-rings but also use two of them. The double o-ring means it literally has twice the sealing surface surface when compared with other push in fittings. This makes these fittings even more reliable and reduces the chance of a leak significantly.
The double o-ring system also means that we can bend the hose with much tighter radius without causing leaking issues. This typically can be an issue with other fittings. This combination of factors makes duotight fittings the most reliable push fit fittings on the market.
No clamps necessary!
We do recommend cutting your hosing straight, not on an angle, to ensure the line has a complete seal. To remove the fitting simply push in the collet and the hose can be removed. These push in fittings are suitable to be used up to 100 psi
Includes Locking Nut (suitable for the TempTwister).
This fitting is ideally used with the TempTwister for a FermZilla or KegMenter for use in the FermZilla Range, Kegmenter range or even drilled into an HDPE fermenter.
What is EPDM?
EPDM = Ethylene Propylene Rubber which has excellent chemical resistance including being compatible with ozone, oils, a wide variety of alkaline and acid compounds, water, alcohol, ketone, and beverages.
EPDM is also resistant to aging, and weather and will not perish easily like other rubber compounds. When compared with silicon and vinyl EPDM has better gas transmission rates, better wear resistance, is BPA free and is the number one choice for many long-lasting food grade applications.

The BlowTie Diaphram Spunding Valve - a great tool if you want to control the pressure retained in a pressure vessel that is releasing pressure. It has been designed for simplicity and ease of putting together. Many brewers use this spunding valve in combination with the FermZilla pressure rated fermenters.
This is the new "BlowTie 2" upgarded model which has the integrated pressure gauge. The adjustment knob on the top of the unit makes it easy to increase and decrease the set pressure. This BlowTie unit can be easily disassembled for cleaning using a screw driver. Designed to suit 8mm (5/16") tubing. It's compatible with both the 4mm ID Tubing or 5mm ID.
This compact solution for adjusting residual pressure in your fermenter makes pressure control easier than it's ever been. This can be used for compressed air, CO2, nitrogen, mains water supply and many other things but its primary use is to control the residual pressure inside fermenters.
Specifications:
1. Suits pressures 0-23psi (but with different gauges the unit can go above 100psi)
2. Made from food grade acetal
3. Stainless screws
4. 8mm (5/16") push on both sides
The design utilises the reliability of the Duotight o-ring system to make sure you can fit hoses to this unit quickly and with leak free connections.
Pressure Fermentations
With the popularity of pressurised fermentation it has become increasingly important to have a method of regulating and controlling this residual pressure from the fermentation process. The BlowTie has been designed specifically for this reason.
Pressure Transfers
When transferring from keg to keg, keg to bottle, or fermenter to keg it is often a good idea to have head pressure in the keg you are filling into especially if you are transferring a beverage that is carbonated. For this reason the BlowTie can consistently control this head pressure giving you more consistent results and without losing carbonation in the process.
Traditional spunding valves that use a simple spring against a seal are flawed right from the beginning as the physical aspects of the design dictate that you will have a significant difference between the opening pressure and closing pressure during operation. Brewers have tolerated this imperfection for long enough and now you can control these pressures far more accurately.
The BlowTie has been made completely differently taking advantage of a diaphragm to actuate the sealing mechanism that will release pressure from the pressure vessel with much more accurate control pressure.
Instructions:
Use the yellow adjustment knob to control the pressure coming out of the pressure vessel. Clockwise is higher pressure and anticlockwise is lower pressure. We would recommend gassing a keg to a known pressure e.g. 15psi then attach your BlowTie Kit to the keg and adjust to 10psi.
These gauges are accurate to about 10% of the range of the pressure gauge. So if you use the lowest range possible it will ensure the best possible accuracy.
IMPORTANT WARNING: Do not exceed gauge pressure. If you set a gauge pressure higher than the graduations on the gauge you can damage the gauge. (ie if you are using the 0-60psi gauge. Do not set pressure above 60psi or damage to the gauge may occur.)

The Duotight Inline Regulator - these compact inline regulators have been designed to suit 8mm (5/16") tubing.
Suits pressures 0-150psi however this unit is packed with the 0-60psi gauge as standard. Suitable for mains water pressure, also suitable for liquid or gas.
- Made from Acetal/POM, EPDM o-rings and stainless teeth
- Suits 8mm (5/16) OD tubing
- Includes integrated 0-60psi Pressure Gauge
For higher pressures such as mains water supply we recommend the 4mm ID Tubing, or 5mm ID if you do not need as high pressures and you would prefer higher flow rate.
This compact solution for adjusting water and gas pressure can be useful in many different applications. It can be used for compressed air, CO2, nitrogen, mains water supply and many other things.
The design utilises the reliability of the Kegland patented Duotight o-ring system to make sure you can fit hoses to this unit quickly and with leak free connections.
These gauges are accurate to about 10% of the range of the pressure gauge. So if you use the lowest range possible it will ensure the best possible accuracy.
IMPORTANT WARNING: Do not exceed gauge pressure. If you set a gauge pressure higher than the graduations on the gauge you can damage the gauge. (ie if you are using the 0-60psi gauge. Do not set pressure above 60psi or damage to the gauge may occur.)

We do recommend using a RAPT Temperature Controller to run this element with the appropriate thermowell or temperature probe attachment.
These electric brewing elements are highly recommended for your HLT, or even for a HERMS or RIMS setup. Multiple elements may be required for larger volumes and depending on what temperature you are trying to achieve. If you are going to be using these elements directly in your mash tun, and will try to maintain temperature using the element, we would recommend getting a power control chip 3600w to modify the power output to the element. Too higher power directly in contact with your malted grain can cause scorching/off flavours as the temperature may not be evenly distributed and isolated purely around the element itself.
