The WD&WL Dual-Rod Grease Gun features a unique dual-rod pressurization design, delivering large grease output volume and fast greasing speed — significantly saving operation time. Compared to traditional single-rod grease guns, the dual-rod structure provides stronger air evacuation capability, removing air faster after refilling to achieve stable grease output more quickly. The discharge tube and gun head use a tapered thread connection that tightens as it’s locked, eliminating oil leakage concerns. The unique trapezoidal thread design ensures easy loading/unloading with superior sealing. The barrel section maintains excellent sealing for both bulk and cartridge grease. The knurled pattern and anti-slip rubber sleeve provide a secure grip for convenient, attractive operation. The T-shaped pull handle effectively overcomes rebound force, delivering exceptionally comfortable handling. The removable rear cover facilitates easy cleaning and maintenance.
The unique dual-rod pressurization design delivers significantly more grease per stroke than ordinary single-rod grease guns. Fast greasing saves time, especially suitable for large-scale equipment maintenance and high-frequency lubrication operations.
The dual-rod structure provides stronger air evacuation capability compared to single-rod designs. After refilling, air is expelled from the barrel faster, achieving stable grease output quickly — avoiding the common “dry pumping” problem of ordinary grease guns and reducing operator frustration.
The discharge tube and gun head use a tapered thread connection design — the more it’s tightened, the tighter the metal seal becomes. This completely eliminates the loosening and leakage problems common with straight-thread fittings, ensuring zero leakage under high-pressure conditions.
The unique trapezoidal thread design is one of the product’s core innovations. Trapezoidal threads distribute force evenly with excellent self-locking properties — smooth and non-binding during loading/unloading, with superior sealing performance compared to ordinary triangular threads. This design ensures long-term reliability and convenience.
The barrel features knurled pattern treatment combined with an anti-slip rubber sleeve — a dual anti-slip design for a more secure grip. Even in oily or wet conditions, slipping is prevented. Convenient to operate with an attractive, professional appearance.
The T-shaped pull handle is key to operational comfort. When applying force with both hands on the T-handle, rebound force during grease output is effectively overcome — delivering exceptionally comfortable handling with minimal hand fatigue during extended work sessions.
The rear cover features a removable design for easy cleaning of residual grease and contaminants inside the barrel. Regular cleaning and maintenance extends product service life and keeps grease output smooth.
The 600CC extra-large capacity allows more greasing work per fill. The automatic mechanism supports flexible grease loading — compatible with both bulk and cartridge grease, adapting to different work scenarios.

WD&WL is a professional hand tool manufacturer with our own factory and comprehensive quality management system. Core processes — dual-rod structure machining, tapered thread precision fitting, trapezoidal thread design — are all controlled in-house to ensure consistent, reliable quality for every dual-rod grease gun.
The unique dual-rod pressurization design is the product’s biggest competitive advantage. High output volume, fast air evacuation, and rapid greasing — work efficiency far exceeds ordinary single-rod grease guns. For professional users requiring extensive greasing operations, this is the key tool for saving time and labor.
The tapered thread’s self-tightening metal seal combined with the trapezoidal thread’s excellent self-locking properties ensures sealing reliability from two dimensions. This completely solves the most common grease gun pain point — oil leakage — giving you confidence under high-pressure conditions.
The T-handle overcomes rebound force, while the knurled pattern and anti-slip rubber sleeve provide dual anti-slip grip security. Even during extended work in oily environments, hand fatigue is minimized — delivering exceptionally comfortable handling.
We support brand logo customization (laser engraving/silk-screen printing), color customization, packaging customization, and capacity specification customization. Our professional team will assist you in developing your industrial tool brand customization plan.
We maintain ample stock for standard specifications with fast shipping after order confirmation. Large orders also come with clear delivery time commitments to keep your supply chain running smoothly.
A: Three main differences: ① Higher output — dual-rod delivers significantly more grease per stroke than single-rod, greasing faster; ② Stronger air evacuation — dual-rod expels air faster after refilling, avoiding “dry pumping”; ③ More comfortable operation — T-handle design overcomes rebound force for exceptionally comfortable handling. Dual-rod grease guns are better suited for high-volume, high-frequency professional lubrication work.
A: The 600CC capacity holds approximately 600ml of grease. Usage duration depends on greasing frequency and amount per application. For typical automotive maintenance (approximately 10-15 grease points per vehicle, 2-3ml per point), one fill can service approximately 20-30 vehicles. For heavy machinery with larger single-application volumes, approximately 8-15 machines can be serviced per fill.
A: Tapered threads have a gradually changing diameter from one end to the other — as they’re screwed in, they tighten progressively, forming a metal-to-metal seal without needing additional sealing rings. Standard straight threads have constant diameter and require sealing rings or thread tape to prevent leaks; over time, aging seals can cause leakage. Tapered threads are better suited for high-pressure, high-reliability applications.
A: Trapezoidal threads offer several advantages over standard triangular threads: ① Larger load-bearing area with stronger capacity; ② Better self-locking properties, less prone to loosening; ③ Higher machining precision for tighter fit; ④ Maintains good sealing even after wear. These characteristics make trapezoidal threads especially suitable for applications requiring repeated assembly/disassembly with reliable sealing.
A: Yes. The barrel features a well-designed sealing structure compatible with both bulk grease and cartridge-style grease. The automatic mechanism supports flexible grease loading, adapting to different work scenarios and user preferences.
A: The removable rear cover facilitates barrel interior cleaning. After extended use, old grease and contaminants accumulate inside the barrel — regular cleaning prevents clogging and keeps grease output smooth. The removable design makes cleaning simple and convenient, requiring no special tools, accessible even for regular users.
A: Knurling creates cross-hatched patterns on the metal barrel surface to increase friction; the anti-slip sleeve is a rubber/plastic covering on the outer barrel providing a soft, non-slip grip surface. Together they form a dual anti-slip design — secure grip even in oily, wet, or gloved conditions, making operation safer and more comfortable.
A: Standard grease gun handles are single-rod straight grips — high-pressure rebound force transmits directly to the hand during greasing, causing hand soreness during extended operation. The T-shaped pull handle has a横向 (cross-bar) design — when applying force with both hands, the torque is greater and force distribution more even, effectively overcoming rebound force for exceptionally comfortable handling that significantly reduces hand fatigue.
A: The dual-rod grease gun’s working pressure typically ranges from 10,000-15,000 PSI, depending on grease viscosity (NLGI grade). For most automotive chassis, heavy machinery, and industrial equipment lubrication needs, this pressure range is more than sufficient. The tapered thread seal design ensures zero leakage under high pressure.
