Most of the times it is easier to just replace a door closer. To improve the physical security of buildings and facilities replacing leaking door closer is necessary. Entrance/exit doors should not close rapidly or with much force to ensure the safety of people who travel at slower speeds or employ differing styles of movement. For replacement closers, consider the following: Closers made of heavy-duty cast iron can stand up to the toughest applications and help prevent leaks. Installation is usually easy – particularly when the closer offers a common hole pattern and fast, accurate install brackets.

First Check The Door Closer
Check for fluid leakage around the closer. You can touch the closer. Is there an oily or sticky feel to it? Oftentimes, a broken closer has leaking oil. Sometimes, a closer is leaking but has not broken fully. If you see oil leaking, the closer must be replaced.
Door Closer Leaking Oil
When the oil drains from the cylinder, the closer’s ability to control the door is lost. If this were to occur, the door would swing freely. There are great service opportunities in replacing the leaking door closer. Door Closers that have oil leaking from the cylinder may present some risk to staff and personal – specifically the potential hazard it presents to those entering and exiting a doorway. The oil inside the closer drips down and can make floors very slippery, not to mention stain the clothing and personal belongings of those passing beneath the closer.
If leaks occur, several options exist to solve the problem. One is to switch to a more durable material structure, such as cast iron. Another option may include moving to the next model size in durability.
Leaks typically occur in two forms: o-ring malfunction or cylinder cracks. One type of o-ring malfunction results from excessive use or abuse of the opening. This can cause the o-ring seal to wear, creating a leak point. A second way the pinion seal can malfunction is most commonly found in aluminum closers with steel pistons. The rigid steel piston can wear on the softer aluminum body, creating tiny metal contaminants – abrasive fragments – that can quickly wear an o-ring. In either case, replacing a pinion seal in the field is not an option.
The other potential malfunction – cracking in the closer cylinder body – may be caused by excessive use or abuse that can create excess internal pressure in the closer. These cracks are often undetected to the naked eye; over time, however, oil will begin to seep through. This condition is also not correctable in the field, and the closer must be replaced.
Reduced door-closer function often creeps up gradually. Building owners may not even realize this until loss of door control occurs. Many closers are not built with heavy-duty construction and materials needed to withstand the constant use of their installed applications. Have Door Closers NYC technicians take a look at each door closer and troubleshot the problem. If oil is leaking from the door closer, it should be replaced.
