Black Silicone Wire Seal Boot

This Black Silicone Wire Seal Boot is made for the spot where a cable leaves an automotive connector. The outer surface is shaped with several grooves, and that's not for looks: once the boot is assembled, those grooves compress evenly against the housing wall. It sits tight between the connector housing and the cable, and moisture, dust and road dirt stay outside the connector.

The material is black silicone, and it handles temperature swings without complaining. It doesn't crack easily or age fast, and it survives repeated flexing. That matters when the part spends its life on a moving vehicle.Color, hardness and size can all follow your assembly needs; send us the drawing and we'll make it to match.

Product Parameter (Specification)

Design Highlights

Look at the ribs on this boot and you'll see they are segmented into several lobes, and that split is deliberate. When the boot is pressed into place, the ribs compress evenly, so the fit is firm but never binding. If the part sits slightly off-center during installation, the ribs absorb the offset instead of tearing under stress.

The silicone is high-purity, so the boot keeps its elasticity over a long service life. Common automotive fluids won't make it go brittle or swell. Dimensions on every groove are held to tight control, which is why sealing performance stays consistent from batch to batch. No surprises when you're running a big order.

It's also meant to go on fast. No special tools, no fiddly alignment: push it over the cable, seat it in the housing, done. It matches standard connector housings and cable diameters, and those saved seconds add up on a production line.

Material & Performance Edge

The compound is automotive-grade silicone, chosen for a part that gets bent, flexed and cycled through temperature changes all day. It also has good compression set resistance, which is a long-winded way of saying the sealing force stays where it should even after the boot has been squeezed for years.

In cold weather it stays flexible instead of going stiff and cracking. On top of water and dust, it shrugs off common grease and oil mist without swelling.

If your working environment is tougher than the standard case, we can change the compound to suit it, and pick a hardness that matches the preload your assembly needs. Just describe the conditions.

FAQ

What is 690161-020 used for? Will it fit my connector?

The Black Silicone Wire Seal Boot protects the cable outlet on an automotive connector—the spot where water likes to creep in.The grooved outer part compresses during assembly and that's what forms the waterproof seal. Whether it fits your connector depends on your housing and cable sizes, so honestly the quickest way to find out is to send us the assembly drawing. We'll check it and give you a straight answer.

Is silicone long-lasting?

Yes. Black silicone stays flexible and ages slowly. But how much heat it can really take depends on the formula, so don't just trust a generic datasheet. Tell us your working conditions and we'll suggest a compound that actually fits.

Can I modify dimensions or hardness?

Hardness and color are the easy part: they're adjusted on the existing mold. Bigger size changes mean a new mold, and we'll confirm the tooling cost and lead time before we start. If you have a drawing or a sample, just send it over.

Can I place a small trial order?

MOQ depends on size and material, so it varies from spec to spec. For a first order, a small trial lot is welcome—we'd rather you test the parts than commit a big order on trust. Once the quality checks out, we re-quote better prices for larger volumes.

How fast are sample and mass-production lead-times?

If the mold is already in stock, samples go out fast. A new mold takes longer, and how long depends on how complex the part is. Either way, we give you both dates, for the samples and for production, right after we receive your drawing, so you can plan around them.

What information do you need for quotation?

A drawing or clear specs, the quantity, and the material you have in mind. That's enough to get us started. If new tooling is needed, we'll include it in the quote. We ship by sea, air or courier, under FOB, CIF, DDP or whatever trade term you prefer.
