Plastic caps have become a common entity in the domestic and business environments today. There is a plethora of commercial and industrial applications for these hardware pieces. But they can also be used for protecting the contents in pipes and tubes while having finishing aesthetics.
Sometimes, plastic caps are called plastic dust caps as they function to cover and protect pipes and tubes which may be exposed to dust and dirt during handling, storage or shipping. With the current technology, plastic caps are well designed today to snap on easily or push-fitted while others are screwed on using the threaded designs. Plastic material is a very common choice for caps due to its versatility of low to high density polyethylene. Hard plastics, silicone or polypropylene compounds and PVC can be generated to produce the plethora of dust caps for the home, office and industrial environment.
The myriad of designs of caps has influenced the lifestyle of consumers today as well as how business operates. Push fit dust caps of plastics can be manufactured in many sizes, shapes, dimensions and colors. These hardware pieces can be flanged or threaded in design with different shapes and sizes in many applications using different colors.
Tapered dust caps can be made of low density polyethylene to function as protective plugs for the inner or outer surfaces of hose and pipes that can be threaded or non-threaded. Using dust caps protect the contents from rust, moisture, dirt, dust and corrosion in any environment over time.
High density polyethylene dust caps have a sealing gasket or disk for leakage prevention as well as offer a more secure sealing and grip. Some plastic dust caps sport a hexagonal top opening or closing to protect tire-stems from dust, debris and dirt as they are made to be weather resistant as well as protect against petroleum-based products.
There are also gas cylinder plastic caps to avoid over-filling and dust from entering during shipment or storage. There is a pull-off tab that is applied for tamper-proofing.
Plastic dust caps are useful in the medical and food cum beverage industry where liquids are capped to prevent the contamination of the consumables. These dust caps of high quality plastics help secure contamination to retain freshness in any bottled products while preventing evaporation or spillage.
