7165-0797 Single Wire Seal

Key Selling Points

Three sealing ribs = triple defense: each rib fits tightly with the hole wall, so even if one point fails, there's still redundancy, making the 7165-0797 single Wire seal more reliable

Automotive-grade silicone, anti-aging: good elasticity, quick rebound, can withstand long-term alternating high and low temperatures and oily environments, not easy to harden or crack

Reliable waterproof and dustproof: Fits connector sealing conditions and meets vehicle-level protection requirements

Flexible specs: through-hole or blind plug options, and wire diameter, hole size, hardness, and color can all be adjusted according to the drawing

Direct supply from the source factory: we handle the whole process ourselves—from materials to molds, molding, and inspection—so delivery time and quality are under control.

FAQ

Q1: Is this sealing plug a through hole or a blind plug? This one is a blind plug — no center hole. It is specially designed to seal off unused cavities in the connector, preventing water and dust from entering through empty ports.

Q2: How's the waterproof performance? Can it handle being submerged or high-pressure water jets? Good question. This series is designed for vehicle connector sealing, so fitted with the housing it keeps water and dust out reliably. An exact rating like IP67, though, really needs to be tested on your actual assembly — we're happy to send samples so you can check it yourself.

Q3: What material is it made of? Is it heat-resistant? Standard version is automotive-grade silicone. It ages well, bounces back, and holds up fine to the heat, cold and oil you see in an engine bay. If your application runs hotter or oilier, we can switch to EPDM or NBR instead — just let us know the working conditions.

Q4: Can the color or hardness be changed? What's the minimum order quantity? Yes to all three — color, hardness, size. MOQ depends on the part; standard items we can run in small lots. Send over the drawing or specs and we'll give you a straight answer.

Q5: How do you ensure that large batches of products have consistent dimensions and no burrs? That comes from the tooling, mainly. One precision mold per part means every shot is identical. On top of that, each batch gets visual and dimensional checks — by hand and by machine — before it ships.

Q6: Can you make a sample first? How long is the delivery time? Absolutely. We'll make samples from your drawing, or from a reference part you send us. Production gets scheduled once you approve the sample. Lead time depends on spec and quantity — share the details and we'll quote you a realistic date.
