Popular Sleeve Options
Shock Cord – Sewn inside hems to secure sleeves to spout openings.
Support Rings – Sewn into the length of sleeves to prevent collapse in negative pressure applications.
Drawstring – Sewn inside hems to secure sleeves to spout openings.
Ground Wire – Sewn inside seam running the length of sleeves to conduct static electricity for improved grounding and safety.
Flanges – Sewn into sleeve ends to allow bolt-on installation to flange plates.
Sift-Sock fabrics can be sewn into virtually unlimited shapes and designs
Cut-to-length fabric tubing in lengths of your choice. Fast, easy, custom length connectors save time and money. Simply fold over the cut ends and secure with hose clamp.
Snap-on “shock cord” hems make installation a snap. Sleeve stays in place during installation; won’t slip off pipe. Secure with hose clamp.
Integrated band clamp hems allows the hose clamp to slide through the specially fabricated top and bottom hems. Easier sleeve installation and better protection against hose clamp cutting of the sleeve material.
Better static control with ClearFlex SDX polyurethane sleeve material. Or, choose stainless steel braided grounding wires.

Materials and Sizes
Siftex Sift-Sock™ fabrics are designed for a variety of applications.

Sifter Sleeves that flex constantly while in use on vibratory and gyratory equipment require a soft, yet durable fabric to maximize wear.
“Load Out” and product transfer sleeves without substantial flex or motion are typically made from stiffer fabrics.
Filter Bags can be fabricated to any dimension from either woven or non-woven media. Natural, synthetic, chemically inert and high temperature materials are available.
Covers for machines, tote bins, drums and hoppers are designed to keep foreign material out and/or to prevent product leakage.

If you can sketch it, Siftex can make it!
First we need the correct measurements.
Here are some tips on measuring to help you get better connected.
Fun with CIRCLE geometry
Diameter = the length of a straight line across the center of a CIRCLE.
Measure the diameter in INCHES.
The outside diameter (O.D.) of the spout you measure is the inside diameter (I.D.) of the spout connector we will supply.
Circumference = the length around the perimeter or outside of a circle, oval or rectangular shape.
Measure the circumference in INCHES
The circumference of a CIRCLE divided by 3.1416 equals the diameter.
A circumference of 25.13 inches = 8 inch diameter.

CAUTION

If you flatten the ends of a flexible connector and measure across the opening, you have measured
1/2 of the circumference or lay flat dimension* not the diameter.
* Lay flat dimension x 2 = circumference. (Divide by 3.1416 and it equals the diameter.)
