The correct combination of hose or flexible tubing with end connections assembled accurately and consistently are the key considerations when aiming to reduce the risk of fluid system leaks, as well as the number of leak points throughout.
Understanding and identifying the correct construction of hose for the media within the system can be safety critical. The end connections adopted can be determined by the versatility/detachability required in balance with the criticality of the fluid in question.
Keep your operations and personnel safe.
Selecting Hose End Connections
Safety and cost effectivity of your fluid system processes is reliant on the right hose with the right end connection.
End connections are where most system leaks occur, therefore selecting the best suited end connection and attachment method will reduce the need for adapters and and the number of leak points that your system is vulnerable to.
Industry standards may already be in place for your application pertaining to hosing and flexible tubing, it's critical that these requirements are adhered to where applicable.
Incorrect or inconsistent hose and end connection combinations can have a serious detrimental effect on fluid system processes, a substantial impact on profit margins and most critically put your personnel at risk.
Identifying the hose end connections required is a vital aspect of ensuring efficient fluid system operations.
Correct Hosing for Application
There are a few general guidelines to note when considering the correct hosing for aspects of your fluid system, however, the majority of the decision making process will be application specific.
General examples of what needs to be considered when selecting hose are aspects such as but not limited to maximum or minimum pressures and temperatures experienced, how inert the the system media is or the flexibility required of the hose.
Having the most detailed understanding of the media within your fluid system is key to selecting the best suited hosing.
Failure to identify the correct hosing requirements for your fluid system can result in extreme situations such as hosing rupture due to lack of pressure tolerance, or material deterioration and media contamination due to chemical reactivity.
Installing the wrong hose within a fluid system can have serious health consequences for operations personnel when subjected to harmful substances and sudden component failure.
Understanding the capabilities of various hose types is critical.
Using the Push-On Tool for Hose End Connections
The push-on hose tool was introduced at the same as the 1" hose was launched, this was due to the high force required to assemble a hose with such a large diameter and wall thickness.
It's important to ensure a straight cut is achieved when preparing the hose, this makes sure the end connection sits perfectly square within the hose and provides an optimal seal. The cut face of push-on hoses will meet the finishing caps on smaller sizes, whilst on 1" sizes the cut face will meet the divider.
When inserting the hose into the jaws of the push-on tool, it's important to ensure that the cut face of the hose sticks out of the jaw by the length of the hose barbs plus an additional 1/2".
Having the hose insufficiently inserted through the jaws can result in damage to the end connection or integrity of the hose, reducing the lifespan of the hose and increasing the risk of contamination with your fluid system.
