duotight – 8mm (5/16”) Female x 8mm (5/16”) Female Push In Elbow

£2.50

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 do we use Double O-rings?
The secret to our superior sealing performance is not just the fact that we use high quality EPDM o-rings but also use two of them.  The double o-ring means we literally have twice the sealing surface surface when compared with other push in fittings.  This makes our 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.

Compatible with our 
- EVABarrier 4mm ID x 8mm OD line
- EVABarrier 5mm ID x 8mm OD line
Not compatible with 6mm ID x 10mm OD line

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.

duotight 8mm Push In Joiner (Double O-Ring) 

This Elbow Piece is suitable for our EVABarrier Beer & Gas hosing in 4mm ID & 5mm ID line or most lines with  8mm outer diameter. 

It will not fit the 10mm OD EVABarrier line (with 6mm ID) but we do sell these larger 10mm duotight fittings separately.

These push in fittings have been engineered for maximised performance in both gas and liquid applications. Compared to other push in fittings on the market, duotight takes the double safety approach to all of the connections with two EPDM o-rings per hose port. No other push ins on the market have EPDM o-rings, let alone two! per push in connection.

What is EPDM?
EPDM = Ethylene Propylene Rubber which has excellent chemical resistance including being compatible with ozone, oils, wide variety of alkaline and acid compounds, water, alcohol, ketone and beverages.

EPDM is also resistant to aging, 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.

Brewing frequently asked questions

How long does it take to brew beer?

The time it takes to brew beer can vary, but on average, the process takes about 4 to 6 weeks. This includes the various stages such as malting, mashing, boiling, fermenting, conditioning, and bottling. However, some beer styles may require longer aging periods for optimal flavor development.

Is home brewing worth it?

Many people find home brewing to be a rewarding and enjoyable hobby, allowing them to create unique and customised beers. It provides a deeper understanding of the brewing process and offers the opportunity to experiment with different ingredients and styles. Additionally, home brewing can be cost-effective in the long run compared to purchasing craft beers. However, it requires time, effort, and a certain level of commitment. Whether it's worth it ultimately depends on one's passion for brewing and the satisfaction derived from the process and the end product.

Is home brewing legal?

Home brewing for personal use is generally legal, and there is no need for a specific license as long as certain conditions are met. Home brewers are allowed to produce beer, wine, and cider for personal consumption. However, there are limits on the amount that can be brewed without a license. As of January 2022, the limits were 100 litres for beer and 100 litres for wine per household.

It's important to stay informed about any updates or changes in the regulations, so it's advisable to check with local authorities or brewing associations for the most current information regarding home brewing laws in the UK. Always ensure that you comply with the relevant regulations and guidelines to enjoy home brewing within the legal framework.
