Inflatable Gaskets
Information regarding the Inflatable Gaskets

Determining Correct Gasket Size

  1. Measure inside diameter of tank in inches (not the lid).
  2. Multiply by 2.54
  3. This is diameter in cm
  4. Choose matching diameter from table. [If diameter lies between two sizes, choose the smaller tube.]

Polyurethane gaskets may seem too small. They can stretch at least 10%.
It is easier to inflate (stretch) the gasket prior to putting it on the lid.

Black Rubber stem is larger diameter than hole in our lid (0.46" vs 0.4"). You must enlarge the hole. Easiest way is to use a step drill bit, available at Home Depot etc. or online at P/N 89315A46.

Inflatable gaskets have 30 day warranty subject to normal use and service.

Air Pumps for Inflatable Gaskets
Periodic maintenance
Remove the valve (black knob in photo) and lubricate orings and end seal.

Please note. Do not overtighten black knob---particularly if it has a teflon tip to make the seal. Teflon "cold-flows". This means it changes shape under pressure. Overtightening will change the shape of the teflon, making it harder to seal in the future.
Pumps for air tubes have 5 day warranty subject to normal use and service.

Teflon Tip and Oring for Drain Port $8
8 mm press fit teflon tip. You must use a mallet to drive it in.

Complete 3-way Valve for Sight Level Tube $130 sold out
The parts above and below should fix any 3-way valve, short of losing one. DN15

Letina Sample Tap Parts
Fits Letina tanks (DN15). Leak can be fixed by replacing either Gasket, Teflon tip, or Oring.
If it leaks around the DN valve connection, it is the Gasket. If it drips from the spout when closed, it is the Teflon tip. If it drips out the end when open, it is the Oring.

Do not overtighten sample taps. This deforms the teflon tip.
Grease sample taps annually. Grease oring, teflon tip, and threads.

Rebuild Kit for Sample Tap $8
Includes teflon tip and oring. (tip is 6 mm press fit)
DN15 gasket is not included.

If you wish to cap off a Letina Sample tap you need DIN15 Round Nut, DIN15 End Cap, and DIN15 gasket. Same items can cap off the level indicator port.

  • DIN15 End Cap $7
  • DIN15 Gasket $5

Rotating Arm for TriClamp Valve
The original simple Rotating Arm—designed, manufactured, and introduced to the wine industry by St. Pat's.
Allows you to drain up to 8" above or below the racking valve of the tank. It is also an answer to a tank with only one valve and the lees at the valve height.

  • Change a fixed height valve into a variable height valve
    Drain tank from up to 8" above or below a racking valve
    Drain tank from up to 8" above the lowest side wall valve.
    Fittings to fit 1.5" or 2" TriClamp
    For new tanks or retrofit any tank
    Simple to operate
    True Stainless Steel Sanitary Fitting--high polish sanitary fitting designed by St. Pats
  • TC Clamp and Teflon Gasket included

The Rotating Arm is an independent fitting that is inserted between the butterfly valve and the tank ferrule. Prior to draining, loosen the TriClamp clamp slightly, rotate the Arm until the drain tube is above the lees, and retighten the clamp. The drain tube can be placed anywhere between 0" and 8" above or below the racking valve. To operate: Loosen the clamp just a little to turn the arm. Then open the valve slightly while turning the arm until the juice is clear, and retighten clamp. You can now drain all the wine that is above the lees.
Leave the arm in the horizontal position when not in use to prevent lees from settling into the arm.

RA150 1.5" $69 in stock in Taylor
includes 1.5" TC Clamp and teflon gasket

How to Determine TriClamp Size

Left photos show position of Rotating Arm (RA200) at same height as valve. Note handle on racking arm (outside of tank) is horizontal.
Right photos show position of racking arm 8" above the valve. Note handle on racking arm (outside tank) is vertical. The arm can be easily rotated to any position between these two positions.
