4PCS 15.5mm Air Compressor Male Thread Oil Plug Boat Tank Vent With Cap Ventilation Function Replacement Suitable For Ordinary Air Compressors

It's not just an oil plug it's your air compressor's protective shield. Precision threading ensures a tight seal, eliminating oil leaks to save you wasted oil costs and prevent costly equipment repairs. Made from high-density plastic, it remains resilient even in industrial environments, resisting oil corrosion and aging for years of reliable service. Three oil plugs provide ample spares, eliminating panic during emergency repairs or future replacements no more rushing to buy single parts mid-repair. Installation is super simple: no tools, no expertise needed just twist to tighten. They fit virtually all piston-type air compressors, saving hours of sizing verification.

• Durable Plastic Material: Anti-aging, built to last 3 years Crafted from high-density engineering plastic, resistant to engine oil, high temperatures, and aging. Remains flexible without cracking over extended use. Outlasts standard plastic oil plugs by 3 times, delivering industrial-grade performance for over 3 years of daily operation. Maintains stable performance under frequent use, eliminating issues of premature aging and brittleness.
• Sealed and leak-proof: Prevents oil seepage to protect equipment. Precision thread design + tight-fitting structure ensures leak-proof sealing for all air compressors. Eliminates common issues of oil waste and pressure loss from old plugs, prevents equipment failure caused by oil corrosion, addresses core oil leakage concerns, and maintains optimal air compressor performance.
• 15.5mm Precision Fit: Compatible with most piston air compressors 15.5mm (0.61 inch) metric external thread + overall dimensions 56x27mm (2.2x1.06 inches) perfectly match most piston air compressors (suitable for industrial/domestic models); Eliminates thread mismatch installation failures or loose seals, resolving core compatibility issues.
• 5-Minute Tool-Free Installation: Beginners can remove old oil plugs by hand without tools or expertise, then align and tighten the new plug onto threads (secure until snug with no play); Complete installation in 5 minutes without damaging compressor threads, eliminating installation difficulties and equipment damage concerns.
• 3-Piece Full-Capacity Pack: One set lasts 2-3 years. Each pack contains 3 oil plugs enough for one compressor (including 2 spares) or separate replacements for three compressors. No need to run out of spares (a common issue with 1/2-piece sets), saving 8 dollar compared to buying 3 individual units; Ideal for workshops, garages, or maintenance teams, eliminating mid-repair replenishment and quantity shortages.
