Introduction |
|
Natural rubber is damaged by fruit juices and many types of rubber and plastic tubing
are damaged by commonly-used
washing/sanitizing chemicals.1 They also contribute
off flavors to wine and beer as the result of flavor scalping
and the bleeding of stabilizing and plasticizing additives (see
Flavor Scalping under the Technical Tab
at the top of this page). The addition of PET-lined, polyolefin
tubing to the BetterBottle product line has enabled BetterBottle to
offer an All-PET solution to home winemakers and brewers;
thereby, eliminating the last major source of undesirable flavors.
The PET lining is hydrophobic and
impermeable, so it washes, sanitizes, and rinses very quickly and
thoroughly (see Washing/Sanitizing under the Technical Tab
at the top of this page). It is no longer necessary to soak tubing
for hours.

Additional Information -
Use the pop up menus associated Tubing
tab at the left side for random access to
additional information relating to the use of PET-lined tubing with
BetterBottle SimpleFlo valves. Scrolling down
this page will access the same information in sequential
fashion.
Chemical Resistance
- In general, avoid very strong
caustics, such as KOH and NaOH (lyes), and concentrated aliphatic
ketones (e.g., essence oils). For additonal materials
specifications, please refer to the Technical tab
at the top of this page.

Description |
|
|
Bev-Seal
Ultra® tubing is FDA sanctioned, NSF-51 accepted,
and specifically designed for transferring beverages. The
seamless PET lining is coextruded with a polyolefin outer tube
using special technology to dramatically reduce the
possibility of de-lamination. |

Use |
|
The PET lining of Bev-Seal
Ultra® tubing is hydrophobic (non-wetting) and extremely
smooth. BetterBottle recommends using the 1/4" ID size whenever
possible for home winemaking and brewing. It is perfect for
BetterBottle systems - it is easy to handle; it fits
SimpleFlo valves, DryTraps, and Universal PET Closure fittings; and
liquid flows through it quickly. It takes only about 9
minutes to transfer 22.7 liters of water through a 1.2 meter (~4')
length of 1/4" ID, PET-lined tubing connecting two carboys that are
equipped with Racking Adapters and SimpleFlo Valves when the empty
carboy is placed on the floor and the full carboy is placed on a
counter 1 meter (~39") above the floor.
The 3/8" ID size makes and excellent blow hose
for very heavy foams and will fit perfectly into BetterBottle
Universal PET Closure. Starting a siphon with either the 1/4" or
3/8" ID tubing is not difficult; however, streaming and air blocking
can be a problem with the 1/2" tubing, because the PET lining is so
smooth and non-wetting. As a rule, the 1/2" size is primarily used
in larger scale operations and to make cuffs to adapt the 3/8" ID
size to 1/2" fittings.

Cleaning /
Sanitizing |
|
Bev-Seal Ultra® tubing is
extremely easy to clean and sanitize. Simply run appropriate
cleaning and sanitizing solutions through the tubing and rinse.
Running the solutions through the tubing will avoid the problems
associated with washing tubing in a bucket (e.g., trapped bubbles,
keeping the tubing submerged, splashing and dribbling, etc.).
Read the Wash/Sanitize section, under the Technical tab
at the top of this page, for important
information.
