This 304 stainless steel air vent valve is an automatic air release component. It’s made for fluid piping systems. It works with a float-driven mechanism. When air builds up in the pipeline, the float drops. The air release port opens automatically to release the trapped gas. Once all the air is gone, the float rises. It seals the port tightly to stop water leakage. A built-in manual knob also allows manual opening of the air release port, enhancing system maintenance or manual venting flexibility.

FAQs of Boiler Safety Connection Group
1. What material is the boiler safety connection group’s insulation shell?
We use EPP for the protective shell material. It costs a bit more than the common EPS white foam on the market, but it has clear advantages for actual use and transportation safety. The key differences are in four main aspects:
High toughness, strong resilience EPS is brittle. It easily cracks and crumbles under pressure or impact, leading to transport damage and customer complaints. EPP has great elasticity and resilience. Even with strong impact or extrusion, it quickly bounces back to its original shape with almost no damage.
Stable performance at high temperatures EPS softens and deforms when the temperature exceeds 70 ℃. It can also age and turn brittle after long use in the high-temperature environment of a boiler room. EPP maintains its structure and insulation performance over the temperature range from -40 ℃ to 110 ℃. It’s a perfect fit for high-temperature scenarios like boiler rooms.
Better appearance and texture EPS has a rough, grainy surface, looking cheap overall. EPP has a smooth surface and dense structure, with a cleaner look and a stronger sense of quality. It’s more in line with the positioning of mid- to high-end products.
Eco-friendly and recyclable EPP is an environmentally friendly material. It’s 100% recyclable. This is a significant advantage in markets with strict environmental regulations, such as Europe and Australia.
2. How to ensure thread precision and consistency in the boiler safety connection group?
Plumberstar uses CNC lathes for thread machining. For different thread standards and specifications, such as BSP and NPT, we’ve created standardized CNC machining programs. These programs have been tested and verified many times. Operators can call them up directly. This avoids deviations and errors from manual programming.
Before each formal production run, we make a first sample. We send it to the quality control lab right away. We perform 3D full-size inspections with CMMs and profile projectors. We check all key parameters comprehensively—like pitch, tooth angle, and tooth depth. We make sure everything fully meets the design drawing requirements. Only after the first sample is confirmed qualified, we’ll start mass production.
During mass production, QA personnel with over 10 years of experience monitor quality nonstop. They conduct random inspections at a fixed frequency: for every 100 products made, they use professional thread-go/no-go gauges to check. This ensures thread accuracy and consistency across the entire batch of products.

4. Can the boiler safety connection group’s packaging be customized?
Of course, we support it.
We can print your brand logo, product model, batch number, and warning signs on the outer packaging and the inner protective parts as needed. Things like moisture-proof, anti-drop, this side up, and so on. You can also provide your own designed labels. They can include SKU codes, barcodes, product descriptions, and relevant certification marks.
We can also customize compliant shipping marks and product instruction labels. It’s based on the destination port’s customs clearance requirements and local regulations. We also support multilingual logo printing to meet the regulatory requirements of different export markets.
If you need it, we can put customized product manuals in the packaging. It makes terminal installation and use much easier.
5. How does the boiler safety connection group simplify wholesalers’ inventory management?
Traditional boiler safety systems usually need you to manage 3–4 separate SKUs. Things like safety valves, pressure gauges, automatic exhaust valves, and mounting brackets. This not only makes sales forecasting and warehouse planning more complicated. It also easily leads to stockouts of some accessories and overstock of others, thereby increasing overall inventory risk.
Plumberstar’s boiler safety connection group set integrates all key components into one complete, pre-assembled product. Customers only need to manage 1 SKU to offer a full set of boiler safety solutions. Compared to selling multiple accessories one by one, this way is easier to manage and better for sales. It also better reflects the value of systematic products, naturally boosting the average order value.
Besides, we can print your exclusive SKU codes and barcodes on the product packaging. After the goods are warehoused, you can scan the code to connect directly to your inventory management system, like SAP or Oracle. No extra secondary operations are needed.
6. Why should distributors choose Plumberstar’s boiler safety connection group?
All our boiler safety connection group sets undergo a 100% air-pressure test before leaving the factory. We screen out all potential defects at the factory first, ensuring no faulty products reach the market. Choose Plumberstar, and you can avoid after-sales costs and brand reputation loss caused by quality problems right from the source.
