FAQs

 How does the drain plug work?

The ADP patented drain plug design has its valve held closed by a stainless steel spring, this valve is sealed by a viton ‘o’ ring when the Femco drainer is attached to the plug outlet it raises the valve allowing the oil to flow down the tube into any container.

 What are the plugs made of?

The plugs are machined from solid brass bar.

 Do I need a drainer for every vehicle?

No. The drainers are designed to fit all of the plugs within a series (i.e. A large standard drainer fits all large standard plugs.)

 Which series should I use?

The series depends on the application, and style of draining.  Standard plugs are common where space is not an issue, compact is used where clearance is a concern. Speed Click is mainly for large fleets or where turn round time is important,
