6in Female x 4in Male Camlock Reducer - Aluminum Cam and Groove Type

In this review the Gloxco aluminum Type DA cam and groove reducer is examined for workshop and field use; it is aimed at technicians and maintenance teams who need a lightweight, corrosion resistant coupling to transition from a 6in hose to a 4in hose. The single biggest reason to consider it is the reliable quick-connect design that pairs a 6in female camlock on one end with a 4in male camlock on the other, reducing connection time and handling compared with threaded adapters while keeping a Buna-N seal for compatibility with fuel and oils.

Key Features

• Type DA configuration: Provides a female camlock on one side and a male camlock on the other to quickly join a 6in hose to a 4in hose without tools.
• Aluminum body: Keeps the overall assembly lightweight for easier handling on lifts or scaffolding while resisting corrosion and abrasion in outdoor or mobile service.
• NBR (Buna-N) seal: Offers compatibility with water, hydraulic oils, coolants and gasoline, reducing the risk of leaks with common fluids.
• Stainless steel cam arms: Durable cam arms include locking cotter pins to maintain secure engagement under pressure and vibration.
• 75 PSI max pressure: Rated for typical industrial transfer tasks where moderate pressure containment is required, matching many hose and pump setups.

Who It's For

This reducer is best for industrial maintenance crews, fluid transfer contractors, and plant technicians who regularly join hoses of different sizes and need a dependable quick-disconnect option. Its aluminum construction makes it especially useful when installers must carry multiple fittings or work at heights and want to minimize weight without sacrificing corrosion resistance.

It is less appropriate for high pressure systems above 75 PSI or for applications needing chemical compatibility beyond what Buna-N offers; teams working with aggressive solvents or very high pressures should consider alternative seal materials and higher pressure-rated couplings.

Pros & Cons

Pros

• Lightweight aluminum body simplifies handling and reduces fatigue during repeated use.
• Buna-N seal provides good resistance to fuels, oils and common industrial fluids for versatile service.
• Stainless steel cam arms with cotter pins secure the connection and resist corrosion.
• Quick cam and groove action speeds up hose changes compared with threaded fittings.

Cons

• Mixed fit reports from users indicate some installations may require minor adjustments or checking mating parts for proper engagement.
• Maximum 75 PSI limits use in higher pressure hydraulic systems.

Frequently Asked Questions

Will this connect a 6in female hose to a 4in male hose?
Yes, the fitting is a 6in female camlock on one end and a 4in male camlock on the other, designed to join those hose sizes directly.

Is the seal compatible with gasoline?
Yes, the NBR (Buna-N) seal is resistant to gasoline, oils and many industrial fluids, making it suitable for fuel handling in typical conditions.

Can it be used above 75 PSI?
No, the fitting is rated to a maximum of 75 PSI; systems that require higher pressure ratings should use a different coupling rated for that service.
