Not all grease fittings are created equal. The material you choose can have a big impact on performance, durability, and safety — especially in demanding environments. Here’s a simple breakdown of the materials we supply and what each is best suited for.
Steel
Best for: General-purpose applications
Steel is strong, affordable, and widely used. It handles high pressure and is ideal for most industrial settings. Zinc-plated versions offer extra corrosion protection, making them suitable for both indoor and outdoor use.
Benefits:
High strength
Cost-effective
Good for standard machinery
303 Stainless Steel
Best for: Outdoor and mildly corrosive environments
303 stainless provides a balance of corrosion resistance and strength. It’s often used in agricultural and construction equipment that faces the elements, but not extreme chemical exposure.
Benefits:
Resists rust in damp conditions
Maintains strength and reliability
Easy to machine and fit
316 Stainless Steel
Best for: Harsh and corrosive environments
This is a higher-grade stainless steel with superior corrosion resistance. It’s commonly used in marine, food, and chemical industries where failure isn’t an option.
Benefits:
Excellent resistance to corrosion
Ideal for marine and washdown areas
Long-lasting and low maintenance
Brass
Best for: Light-duty or non-magnetic applications
Brass fittings are naturally resistant to corrosion and are non-magnetic. They’re easy to work with and a good fit for light industrial or specialist equipment.
Benefits:
Resists rust without coatings
Safe for low-pressure systems
Non-magnetic – useful in sensitive equipment
Monel®
Best for: Extreme environments
Monel is a high-performance alloy known for its durability. It works well in severe conditions, from offshore rigs to heavy industry, where other materials might fail.
Benefits:
Tough and corrosion-resistant
Performs under pressure
Trusted in the marine and chemical sectors
Phosphor Bronze
Best for: High-wear and safety-critical settings
Phosphor bronze is chosen for its excellent wear resistance and non-sparking properties. It’s strong under friction and pressure, making it ideal for rail, mining, and explosive environments.
Benefits:
Withstands friction and heavy loads
Long service life
Non-sparking – safe in hazardous areas
