FTH, short for Failure to Hold, is a technical term commonly used in the manufacturing industry, particularly in the context of nipple/sidepocket assembly. It describes a specific type of failure that occurs when a nipple, which is a small, projecting part, is unable to properly secure itself within a sidepocket, a recess or cavity designed to receive it.
Understanding FTH
The root cause of FTH can vary depending on the specific application. Here are some common factors:
Consequences of FTH
FTH can have serious consequences, depending on the product and its intended use. These include:
Preventing and Mitigating FTH
To prevent and mitigate FTH, manufacturers can employ various strategies:
FTH: A Critical Consideration
FTH is a crucial consideration for manufacturers across industries. By understanding the causes, consequences, and prevention methods of FTH, companies can improve product reliability, enhance safety, and minimize production costs.

Scenario: You are working in a factory that manufactures automotive parts. One of the products is a fuel pump assembly that uses a nipple to connect the fuel line to the pump. Recently, there has been a rise in FTH issues with this assembly, leading to fuel leaks and potential safety hazards.
Task: Identify three potential causes of the FTH issue and propose specific solutions for each cause.
Here are some possible causes and solutions:
Cause 1: Improper fit between the nipple and sidepocket: * Solution: Implement a more rigorous inspection process to ensure proper dimensional tolerances of both the nipple and sidepocket. Additionally, consider using a different type of nipple or sidepocket with a more secure design.
Cause 2: Material incompatibility: * Solution: Test different material combinations for the nipple and sidepocket to find the optimal pair that provides the best adhesion and friction. Consider using materials with higher strength and resilience.
Cause 3: Vibrations during assembly or product use: * Solution: Introduce vibration dampeners during assembly or product use. Consider using a different assembly technique that minimizes the impact of vibrations on the nipple and sidepocket connection.
