A TriClamp connection consists of two Ferrules joined by a Clamp with a Gasket.

How to Determine TriClamp Size
TriClamp Size is determined by the outside diameter of the pipe, NOT the outside diameter of the ferrule. The ferrule ( the end piece that makes half of the connection to another TC fitting) is about 1/2" larger than the TC size. In other words, a 1.5" TC fitting will have a ferrule whose outside diameter is about 2". Confusion arises with 1" TC fittings because they use the same ferrule as 1.5" TC fittings. [The two ferrules at right in photo are 1.5" and 1" Triclamp.]

1" and 1.5" TriClamp use the same clamp. The 'ferrule' is the same. The difference is the pipe diameter. To demonstrate, a 1" Tee is attached directly to a 1.5" Tee.

Replacement Seats
If you have red or black seat, order either red or black. Red and black are interchangeable.
(Older valves. If you bought valves several years ago from us, then you may have white seat. You MUST order white seat. )
White is silicone. Red is silicone. Black is EPDM.
Note that these seats work only with St. Pats valves.

ULTRA Sanitary Butterfly Valve
Easily dissasembled for cleaning. Valve body is held together with a clamp. This valve is typically used in food processing with stringent sanitation requirements (for example, the valves are disassembled and cleaned after each process run.)
The difference between Ultra Sanitary and standard butterfly is that a clamp, rather than bolts, hold the valve body together.
Trigger handle (6-positions in 90°).

Ball Valve for Wine
Teflon seats. Long, solid stainless handle.
Best quality ball valve in the wine industry.
304 stainless steel.
Please note. Do not mix seats between valves---this may cause leaks as the teflon will slowly form itself to its original valve. Teflon "cold-flows". This means it changes shape under pressure. Teflon seat will last virtually forever if it remains with the original valve.

Clamp (heavy duty single pin)

304 stainless, not 202 stainless. Some clamps on the market are produced from cheaper 202 stainless (although suppliers are mistakenly listing them as 304). This can be easily checked with our X-Ray Fluorescence analyzer.

90° Rubber Hose Adapter (TC x hose barb)
Be careful when ordering. The first number is the TC size and the second is the hose barb size.
If you use two clamps, apply the clamp furthest from the hose end first. Then apply the second with the buckle at 180° to the first. A single clamp will suffice in many applications and with small diameter hose.

Be careful when ordering. The first number is the TC size and the second is the hose barb size.
Long ends for use with Brewers hose (we do not sell brewery hose). Brewery hose adapters are generally not needed for Nutriflex/Nutriflo.
It is easier to clean the lip of the fitting (inside the hose) with the standard rubber hose adapter than with the longer adapters.

Tri-Clamp Gaskets
made from FDA approved materials

EPDM is fine for most applications with a working temp range of -40 F to 300° F. EPDM generally has better resistivity to cleaning chemicals than silicone.
Silicone working temp range is -90 F to 480 F.
Teflon (-10 to 300°F) is the best choice only for highly corrosive environments which does not include beer or wine.
Buna: We do not offer Buna. Buna is best suited for petroleum industry (gasoline). Buna temp range is narrow (-25 to 225° F) and has the worst rating for steam cleaning. In addition, Buna generally has lower ratings for chemical resistivity than EPDM or silicone.

Garolla Fittings

Garolla is the Italian equivalent of TriClamp. You will find these on some Italian equipment. [Please note that all Italian equipment sold at St. Pats terminates in TriClamp, not Garolla.

How to Determine Garolla Size
Garolla is the Italian equivalent of TriClamp. The ferrule of garolla is tapered so the sizing is not nearly as apparent as with TriClamp. Here are the dimensions.
