Yes, Siftex products noted as FDA Acceptable are in compliance with the applicable Code of Federal Regulations (CFR).
No, Siftex products which are identified as “FDA Acceptable” does not mean they are
“FDA Approved”. The Food and Drug Administration is the US Federal Agency responsible for ensuring that foods are safe, wholesome and sanitary; human and veterinary drugs, biological products and medical devices are safe and effective; cosmetics are safe; and electronic products that emit radiation are safe. Before a new drug or medical device is introduced, the manufacturer must demonstrate its efficacy to the FDA and, if it passes, it must be formally approved by the FDA prior to its use.
However, the FDA does not have an approval process for thousands of products, including flexible connectors, screening cleaning devices, dust-control items and more which come into direct contact with food. The FDA does not review the composition of these products before they enter the market, nor do they inspect, test, or approve them. What the FDA does provide is an exhaustive set of regulations (Code of Federal Regulations) which govern the formulation, manufacture, and use of products intended for use in direct food contact.
As a result, the onus of compliance to these regulations is placed on the manufacturers of these products. It is for the manufacturer of the finished product intended for direct food contact to demonstrate compliance by issuing a FDA certificate. It is also important to note that while a component may be made from a FDA material that is suitable for food contact; this does not mean that the part is technically suitable for its intended application. It is the responsibility of the product user to determine if the part is acceptable for the intended use.
Because it is the manufacturer that is responsible for complying with the regulations when producing a product for use in direct food contact and not the FDA that approves the product once it is manufactured, the correct terminology is that a product intended for use in direct food contact is “FDA Compliant” or “FDA Acceptable”, not “FDA Approved.”
Typically, no. Unreinforced polyurethane, rubber, vinyl and fabric sleeves will balloon in even low (0.5 psi) pressure applications. Most Siftex products are designed to be used at atmospheric pressure. Siftex does offer many types of pressure rated connecting sleeves and hoses.

a. If the connector is round: measure the distance directly across the center of the pipe or duct.
This is the diameter. If the pipe has any “flare” or expanded area which the connector must fit over,
be sure to include this in your measurement.
If you cannot measure directly across the pipe, measure the distance around the outside of the pipe (at its widest point if there is a “flared” end). This is the circumference. The circumference divided by 3.1416 equals the diameter.
If you cannot measure either the diameter or circumference, but you have a flexible connector which fits the opening. Lay the flex connector flat on a table. Measure the length of the flattened opening.
This measurement is one-half the circumference. Multiply this by 2 and divide by 3.1416 to calculate the diameter.
b. if the connector is to fit on an oval: first determine the circumference.
For example the circumference of an 8” x 16” Oval:
1. Multiply smaller number by 3.1416.
8 x 3.1416 = 25.1328. This is “A”.
2. Subtract smaller of the two numbers from the larger.
Multiply by 2.
16 – 8 = 8. 8 x 2 = 16. This is “B”.
3. “A” + “B” equals the Circumference
25.1328 + 16 = 41.1328
4. Circumference divided by 3.1416 = the diameter.
c. if the connector is to fit a rectangular opening: determine the perimeter by adding the length of the four sides. For example, a 12” x 24” opening has a perimeter of 12+12+24+24=72. The equivalent diameter which will fit this rectangular opening is 72 divided by 3.1416 = 22.9 inches.
The connector length is the sum of three factors: the distance between the pipes being connected + the length required for clamp attachment at both ends + the “throw” (offset motion) of the equipment. For example, if you have a 12” distance between the two pipes, plus there is 1-1/2” of length on each pipe for clamp attachment, and the machine has a 1” offset motion, then the connector length should be 12+3+1 = 16 inch connector.

Conductive = zero resistance to electricity flow; Dissipative= resistance below 1 gigOhm (1×109) such that the electrical charge moves through the material and dissipates into the atmosphere. There is not enough resistance to allow the charge to build up to the point of generating a discharge (spark).
