Should you spend the extra money on high quality hose?

Posted by Morgan Byres on

One of the most common questions asked is “what hose should I buy”. Like most questions about brewing, the answer is never universal. Fortunately, we’ve broken the various options down into bite-sized chunks and provided three options.

When it comes to choosing hoses there are a couple key things to consider:

  • Are product contaminations a concern?
  • Will the hose be at risk of being crushed?
  • Will the hose be under a high vacuum?
  • What temperatures will you be working with?

These four factors should then guide your consideration of what choices to make with your hose - from crimping vs. band clamps, to material selection, and more.

Band Clamp vs. Professionally crimped Tri-Clamp ends

Band clamping is cheaper and it gives you the ability to remove your end and attach it to a new hose. However, band clamped hose brings with it a higher risk of infection and has a higher rate of failure than professional crimping. Band clamped hoses are only held in two areas, instead of along the entire length of the Tri-Clamp insert. This produces a space which is hard to clean during CIP, storing bacteria and grime ready to attack your next batch. Further, since the hose is only held in one or two places there’s less friction holding the end on, resulting in a higher risk that pressure within the hose will knock the end clean off. This kind of failure can be disastrous.

When a hose is professionally crimped the entire length of the tri-clamp insert is crimped against the inside of the hose. This creates a sturdy end that will not be pushed of by pressure. The smooth internal bore leaves no space for bacteria to grow, the entire hose can be fully sanitized during CIP.

What material do you want?

Your choice of material is going to depend entirely on the temperatures you’re working with and the product you are pumping. Butyl, chlorobutyl, and EPDM are all food grade and appropriate for breweries and other craft food and beverage industries, but if you are moving high-temperature products an EPDM hose is recommended. EPDM can handle up to 300°f, while butyl and chlorobutyl can “only” handle up to 220°f.

Making the choice - Hose options:

At CPE we’ve worked with a large selection of hose. In this time we’ve settled on three hoses which we think provide the best options for brewers and beverage makers.

 

 

Contitech Vintner Hose

Our favourite hose is still Contitech vintner hose. Crushproof and able to keep its shape even with harsh vacuum, but also flexible and easy to work with, Vintners has won us over.  Its main draw is that it avoids metal spirals, which are inflexible and can rust, and instead uses a spiral plied synthetic fabric with polyester monofilament helix. This results in a hose that is crush resistant, doesn't corrode or rust, and tends to spring back to shape when crushed.

Brewers Hose

While not as crushproof as other options, Brewers hose is both kink and light vacuum resistant. If you’re not worried about full vacuums or crushing, it is a fantastic hose that will serve you a long time.

EPDM Brewers Hose

If heat is a concern, you’re not going to beat EPDM Brewers hose, it is ideal for transferring hot products (up to 300f). The hose is comprised of seamless white EPDM and covered with a grey EPDM sleeve. Two polyester spirals with dual helix wire maintain the shape of the hose. It is a strong sturdy hose that can withstand a full vacuum and is bacteria and abrasion resistant.
