Description
Overview:
The Universal Spark Plug Cap for HT Leads is a durable rubber cap that connects the spark plug to the high-tension (HT) lead on small petrol engines. It insulates the connection, helping to prevent arcing and misfires, and seals out moisture and dirt to protect the ignition system. Built for regular use, it suits a wide range of construction and garden machinery such as lawn mowers, brushcutters, chainsaws, generators, plate compactors and cement mixers. The cap includes an internal clamp insert for secure attachment to the HT lead, and pushes firmly onto the spark plug terminal for a reliable fit. Its universal design supports everyday maintenance and repair, helping keep engines starting reliably and running smoothly in both professional and DIY settings.
Key Features:
- Robust rubber construction for long service life in tough outdoor conditions
- Excellent electrical insulation to reduce the risk of arcing and misfire
- Weather-resistant seal helps keep out water, dust and debris
- Clamp-insert design for quick, straightforward fitting to the HT lead
- Firm grip on the plug terminal for a stable, vibration-resistant connection
- Universal fit suitable for many small 2‐stroke and 4‐stroke engines
- Supports consistent starting and smoother running under load
- Easy to remove and refit during routine spark plug checks and replacement
- Lightweight and compact to route neatly in tight engine bays
- Cost-effective maintenance part to restore reliable ignition performance
Typical Applications:
Used on small-engine equipment across landscaping and construction: lawn mowers, strimmers/brushcutters, hedge trimmers, chainsaws, generators, pressure washers, rotavators, tillers, cut-off saws and plate compactors. Ideal for replacing worn, cracked or loose caps during servicing to maintain good ignition, especially in wet or dusty working environments.
Also known as:
Spark plug boot, HT lead cap, ignition lead cap, spark plug connector, plug cap, ignition boot. These terms refer to the same component that covers the spark plug terminal and links it to the high-tension lead in small petrol engines.
