Back-Up Washers for Strain Relief Bushings provide additional support when panel is very flexible, thin or has a U-shaped opening. Made from zinc-plated steel, back-up washers come in three sizes.

HEYCO® Grommet Lab Kit #7 is perfect for product design departments, experimental labs and all prototype work.

High Temperature Flanged Bushings, also known as "shoulder washers" or "insulation sleeves", are excellent insulators because they are molded from nylon and are impenetrable by moisture, dirt and most chemicals.

These Snap Bushings for Thicker Panels convert raw-edged holes to smooth, neat, insulated holes in 1/4" (6.40mm) thick panels. They insulate and mechanically protect electrical and telecommunications cables, tubing, hose, rope and utility lines. These bushings are available in 10 sizes for use in 1/2" - 2" (12.70mm - 50.80mm) diameter holes.

Metric Insulating Snap-In Bushings convert raw-edged holes to smooth ones. They are available in four sizes for use in 16.00 mm (0.630") to 32.00 mm (1.260") diameter holes. (For other metric sizes, contact EFC International directly)

The Open/Closed Split Bushing design allows side entry and encirclement of pre-assembled harnesses, capillary tubes or other assemblies that have segments larger than the bushing's ID.

Open/Closed Universal Bushing have a split design which allows side entry and encirclement of preassembled harnesses, capillary tubes or other assemblies that have segments larger than the bushing ID. They are constructed from Nylon 6/6, and are available in 9 sizes for use in 1/2" to 1-1/2" (12.70 mm to 38.10 mm) diameter holes.

Short Nylon Snap Bushings are insulating feed-through bushings for limited internal clearance applications (minimum 0.125" or 3.20mm). They insulate and isolate electrical or telecommunications cables as well as low RPM shafts and push-pull rods. These bushings are available in 17 sizes for use in mounting holes from 3/16" - 1" (4.70mm - 25.40mm).

Short Universal Bushings are ideal for applications with limited internal clearance. Fingertip pressure snap-locks these bushings into their mounting hole. Flexible "shutters" adjust to accommodate and support any shape from 0.125" to 0.560" (3.20 mm to 14.20 mm).

Snap-In Grommets, also called "Sleeve Bearings", are easy-to-use bushings. They have a flange at the top and bottom to provide better anchoring and support.

Standard Nylon Snap Bushing converts raw-edged holes to smooth, neat, insulated holes. Their locking fingers "snap" into holes with simple fingertip pressure. They insulate and mechanically protect electrical and telecommunications cables, tubing, hose, rope and utility lines. They are available in 58 sizes for use in 1/4" - 6" (6.40 mm - 152.40 mm) diameter holes. Three parts are available in brass color for lamp and lighting applications.

Standard Snub Bushing provide light strain relief and insulation. They are suitable for 1/8" to 1/4" (3.20 mm to 6.40 mm) diameter cable, tubing or hose.

TAPERED FLANGED BUSHINGS have the advantage of being inexpensive, light weight, low friction, non-corrosive and of possessing excellent compressive and tensile strength. They are suitable as light-load bearings or bushings.

Threaded Insulating Bushings convert raw-edge pipe ends with NPT threads to smooth insulated ends.

UNIVERSAL BUSHING FOR THICK PANEL convert raw-edged holes to smooth, neat, insulated holes in 1/4" thick panels. They are constructed from 6/6 Nylon, and come in 8 sizes for use in 1/2" to 1-1/2" (12.70 mm - 38.10 mm) diameter holes.
