E-SEEL® Boots

3 to 4 threads (maximum) for

all toggle pushbutton

and rotary shaft seals

(except N5000 series).

2 to 3 threads (maximum) for

For proper installation of these boots, follow these five sequential

steps. It is EXTREMELY IMPORTANT that the number of threads on

Failure to respect these maximums may result in boot damage

(such as tearing).

STEP 2. Put threaded bushing through panel.

STEP 3. Adjust back-up nut to allow the specified number of threads

to protrude past front of panel (see Dimension “A” above).

STEP 4. If needed, install appropriate bushing adaptor.

STEP 5. Install switch boot in place of front mounting nut.
