Dust cap set for Flat Face Hydraulic quick coupler Bobcat skid steer (4 Sets)

1/2" FLAT FACE HYDRAULIC COUPLER DUST CAP SET (4-PACK)

Keep your entire fleet's hydraulic systems protected with this comprehensive 8-piece set of high-durability dust caps. Specifically engineered for standard 1/2" body Flat Face (ISO 16028) couplers, these caps provide the essential barrier needed to prevent hydraulic system contamination—the #1 cause of pump and valve failure in skid steer loaders.

🗸 PREMIUM SILICON RUBBER CONSTRUCTION: Built for the harsh conditions of professional job sites, these caps are highly resistant to oxidation, UV degradation from direct sunlight, and exposure to aggressive hydraulic fluids or solvents. They remain flexible in extreme cold and will not harden or crack over time like low-grade plastic caps.

🗸 PRECISION-MOLDED FOR ISO 16028: Designed specifically for 1/2" Flat Face couplers. The precision-fit ensures an airtight seal that stays firmly in place during heavy vibration, transport, or machine operation, preventing debris from accumulating on the sealing face.

🗸 MULTI-MACHINE PROTECTION: With 4 complete sets (4 male + 4 female caps) included, this is the perfect solution for shop management, allowing you to protect your loader’s auxiliary ports and multiple attachments simultaneously.

🗸 FIELD-READY DURABILITY: The robust design ensures they can be removed and replaced thousands of times without tearing, providing long-term reliability for operators who perform frequent attachment changes.

Specifications

Q: Are these compatible with AG-style (ball-detent) couplers?

A: No. These are specifically designed for ISO 16028 Flat Face couplers. They will not provide a secure fit on AG-style couplers. Please ensure your couplers have a perfectly flat surface before ordering.

Q: Why do I need to keep the flat face clean?

A: Even a microscopic amount of grit trapped on the flat face can compromise the O-ring seal once connected, leading to high-pressure leaks. Furthermore, when you connect the coupler, any dirt on the face is pushed directly into your machine's hydraulic oil, where it can travel to and damage your main pump and valve block.

Q: How do these hold up in freezing temperatures?

A: Because they are manufactured from silicon rubber, they retain their elasticity in sub-zero temperatures. Unlike plastic caps that become brittle and prone to snapping in the cold, these will remain flexible and easy to remove/install year-round.

Q: Can I use these on bulkhead-mounted couplers?

A: Yes. In fact, they are ideal for bulkhead-mounted couplers where the connection points are exposed to road salt, mud, and dust while the machine is traveling between sites.
