Project Ideas
Business
Mobile On-Site Lubrication Service
Offer scheduled greasing for fleets, farms, and construction equipment. Equip each tech with a cordless grease gun and multiple heavy-duty couplers to handle different access situations. Sell tiered plans (monthly/seasonal), document each zerk point serviced, and reduce client downtime with proactive PM.
Remote Grease Point Retrofits
Audit customer machines, then install remote grease lines and protective caps to bring hard-to-reach zerks to safe locations. Use the 1/8 in. NPT couplers for quick connection during service. Provide a labeled map of all points and a maintenance schedule; charge per-point plus a service contract.
Grease Gun Upgrade Kit Micro-Brand
Bundle premium 3-jaw couplers, whip hoses, thread adapters, dust caps, and a cleaning needle into a branded kit. Sell online with how-to videos showing clean coupler engagement and leak-free greasing. Offer subscriptions for consumables and fleet bundles with volume discounts.
Technician Training Workshops
Run short courses for small shops and co-ops on proper greasing techniques, coupler selection, and troubleshooting noisy or starved bearings. Provide a practice rig with multiple fittings, include a take-home coupler set, and upsell tools. Partner with vocational schools and equipment dealers.
Lube-in-a-Box Rental
Rent a portable case containing a cordless grease gun, multiple couplers, adapters, a small parts tray, and safety signage to small contractors or event crews. Offer weekend and weekly rates, optional on-site demo, and a refill/cleaning service between rentals.
Creative
Click-Coupler Fidget Block
Create a desk toy that uses spare zerk fittings mounted in a metal or wooden block. The 3-jaw grease couplers provide a satisfying snap-on/snap-off action as you click them onto the zerks. Add color-coded zerks and a rotary wheel to change positions. Keep everything clean (no grease) so it’s a tactile, industrial-style fidget.
Industrial Pipe Lamp with Coupler Accents
Build a steampunk-style lamp using black iron pipe and fittings, then feature the zinc-plated 3-jaw couplers as eye-catching mechanical nodes or switch surrounds. The couplers’ knurled ends add texture and a purposeful aesthetic; use 1/8 in. NPT adapters to mount them as decorative caps or cable guides.
Lubrication Learning Board
Assemble a wall-mounted teaching board with various hydraulic-type grease fittings, cutaway components, and a hand grease gun. The couplers let learners feel proper engagement, alignment, and safe removal. Include labels, a small gauge, and mock ‘restricted’ fittings so users can practice troubleshooting without high pressure.
Quick-Change Thick-Fluid Applicator
Adapt a manual syringe or small hand pump to 1/8 in. NPT and use the coupler as a quick-connect nozzle to swap between tips for applying thick pastes (wood glue gels, gasket maker, compound). Build a tip rack with different orifice sizes; the coupler’s jaws let you click on the right tip fast.
Clay/Putty Extrusion Dies
Make a set of small extrusion dies threaded for 1/8 in. NPT and use the coupler on a manual grease gun loaded with soft clay or putty. Create patterns (stars, ropes, ribbons) for pottery or crafts. Use low pressure and soft media; the coupler makes swapping dies quick and tidy.
