Slippery Pete 90° Grease Gun Coupler with 18" Flex Hose — 31mm Head, Swivel & Four-Jaw Lock

Slippery Pete’s 90 Degree Grease Gun Coupler with an 18" flexible hose is a right-angle, threaded grease gun adapter with a 31mm head, swivel connection, and four-jaw locking coupler for secure, leak-reducing lubrication in tight spots.

Designed for home mechanics, shop technicians, and anyone who maintains machinery, this angled grease coupler combines a compact 31mm head and a threaded inlet that mounts directly to the included 18-inch flex hose. The swivel joint gives movement freedom while a four-jaw, adjustable locking mechanism snaps securely onto Zerk fittings to minimize drips and lost grease. Built to withstand workshop use, it simplifies access to recessed or obstructed grease zerks on vehicles, equipment, and agricultural implements.

How does the 90° angle help when greasing confined spaces?

The right-angle head lets you approach fittings that a straight coupler cannot reach without bending hoses or disassembling parts. It positions the grease flow parallel to surfaces and around obstructions so you can work in wheel wells, frames, and other tight cavities. The relatively short 31mm head balances reach with clearance, avoiding interference with surrounding components.

• Accesses recessed Zerk fittings where straight couplers snag
• 31mm head prevents binding against surrounding parts
• Reduces need to reposition machinery or remove panels

Will this coupler leak or come loose during use?

The coupler’s threaded inlet connects directly to the included 18" flex hose, eliminating intermediate fittings that commonly leak. Its adjustable four-jaw locking mechanism clamps onto standard grease fittings to hold a secure, drip-resistant seal while you pump. The swivel connection further prevents stress on the hose and fitting, cutting down on accidental disconnects.

• Threaded inlet reduces leak points between hose and coupler
• Four-jaw adjustable clamp for consistent, tight grip
• Swivel reduces torsion and hose strain during operation

How durable and serviceable is the Slippery Pete coupler?

Constructed for repeated workshop use, the coupler is made from materials chosen for wear resistance and longevity under pressure. The mechanical jaw design is simple to maintain; debris and hardened grease can be cleaned from the jaws and swivel area quickly. Because the inlet is threaded, replacing the flex hose or coupler independently is straightforward if parts show wear.

• Robust jaw and swivel components resist workshop wear
• Threaded connections allow easy part replacement or hose swaps
• Simple cleaning keeps operation smooth over extended use

What grease gun types and fittings does it work with?

This adapter is compatible with common grease guns using standard threaded inlets and accepts most Zerk/grease nipple styles thanks to its four-jaw clamp. It is intended as a general-purpose right-angle solution for petrol/diesel vehicle maintenance, lawn and garden equipment, industrial machinery, and agricultural gear. Confirm your grease gun’s inlet thread matches the coupler thread for a direct, secure fit.

• Fits standard Zerk grease fittings with snap-on four-jaw action
• Threads directly to matching grease gun hoses or fittings
• Suitable for automotive, equipment, and farm maintenance tasks

Who this is for: The Slippery Pete 90 Degree Grease Gun Coupler is ideal for DIY mechanics, garage technicians, fleet maintainers, and farm hands who routinely service hard-to-reach grease points. If you need a compact right-angle tool that reduces leaks, resists shop wear, and simplifies access to recessed fittings without disassembly, this threaded, swivel-head coupler with an 18" flex hose is built to speed routine lubrication and reduce mess.
