There is an "insertion confirmation line" to check for insufficient insertion, providing peace of mind. 【Features】 ■ Suitable for prefabricated construction methods ■ Lightweight design ■ Superior flexibility compared to conventional piping materials ■ No special tools required, allowing the hose to be bent freely ■ No worries about leaks due to all-prefabricated construction methods *For more details, please refer to the PDF document or feel free to contact us.

Proposal for Air Conditioning Drain Pipe Testing Methods - From Water Pressure Testing to Air Pressure Testing - Traditionally, the only method for quality confirmation after the installation of air conditioning drain pipes was water flow testing. However, incidents of leakage at connection points have occurred, leading to an increase in the implementation of full water tests. Nevertheless, these methods often struggle to detect minute leaks and require significant effort for water preparation and treatment necessary for testing. Moving forward, to streamline operations on-site, we believe that a high-precision "waterless testing method" using the latest "digital pressure recording inspection device" will be effective. Ishiguro Co., Ltd. proposes a new testing method using a pressure insertion integrated testing jig (air seal tester) and a test closure valve, which allows for simple and quick air pressure testing of drain pipes. Four Major Benefits of This Testing Method: ■ Digital air pressure testing has a higher leak detection accuracy than water pressure testing! ■ No need for the hassle of transporting water or treating water after testing! ■ Testing time is reduced to 15 minutes, making it faster! ■ Automatic recording of pressure changes and leak judgment results!

■The independently developed "self-sealing" structure eliminates the need for sealing water. ■The trap section can be easily removed for cleaning. ■The valve structure has been changed to an umbrella type. ■It has become a model compatible with both vertical and horizontal piping. ■It also supports intermediate piping and end piping specifications. ■An outdoor version has also been added.

■Fewer parts compared to other hose fittings ■Good usability when inserting the hose ■Equipped with an insertion confirmation window to prevent insufficient insertion ■More secure connection that is less likely to come off compared to bamboo shoots + hose clamps, as well as low pressure loss.

■Beautiful casting surface made with full-scale lost wax production ■OEM production commissioned to domestic manufacturers ■Equipped with static electricity prevention device

■Due to its simple structure, it is affordably priced. ■It is very lightweight and easy to use.

We have five types of products in stock. Other calibers and sizes can also be produced. However, prices and delivery times may vary depending on the order quantity.

The "Easy Drain Hose Soft" is an insulated hose (with fittings) for the drain up-piping of packaged air conditioners. Conventional products could only be installed using rigid PVC fittings with adhesive connections, but the soft type uses flexible PVC fittings with band-clamp connections. Similarly, it employs transparent resin, allowing for visual confirmation of the insertion length of the pipe and the water flow condition after installation. Moreover, despite being a flexible fitting type, it is detachable and allows for hose rotation, enabling the use of a closure cap and accommodating air-tightness testing after installation. 【Features】 ■ Fittings are band-clamp connections (adhesive not allowed), detachable, and can rotate 360 degrees (only on the primary side) ■ Can be directly connected to AC drain pipes of 20A ■ Can be directly connected to AC drain fittings of 25A Note: When connecting directly to the indoor unit, please follow the installation manual of the indoor unit.

In April 2021, we began selling the reduced bore type. The full bore type was added in April 2022. The reduced bore type is available in lever handle and butterfly handle styles. The full bore type is only available in the lever handle style. These ball valves are ideal for stainless steel piping in industries such as food, pharmaceuticals, and paper manufacturing, offering quality comparable to domestic manufacturers at a more affordable price. We hope you will take advantage of them.

The "Easy Drain Hose" is an insulated hose (with fittings) for package air conditioner drain up piping. The fittings are connected with adhesive and made of rigid PVC. By using transparent resin, the insertion length of the pipe, the application status of the adhesive, and the water flow condition after installation can be visually confirmed, significantly improving construction quality. Additionally, a lock ring has been added to prevent incorrect reassembly when the snap ring is removed. 【Features】 ■ Fittings are adhesive-connected, detachable, and can rotate 360 degrees ■ Can be directly connected to AC drain pipes ■ Hose fittings can be connected to AC drain fittings ■ A new red "lock ring" has been added Note 1: When directly glued to the indoor unit, there may be models that cannot be glued, models with drain openings larger than the drain up hose, or models that become thicker partway through, so please be careful. Note 2: This product is made of PVC resin, so if stored in high-temperature environments, it may deform and not perform as intended. Please avoid storing it in vehicles during the summer. * For more details, please refer to the PDF document or feel free to contact us.

We conducted seismic tests simulating the maximum expected earthquake, a direct-type earthquake with a seismic intensity of 7, and confirmed its effectiveness (1.2 times the intensity of the Hanshin Earthquake reproduction wave). Due to its lightweight design, it reduces work time, requires no tools, and can be installed with just one item, eliminating mistakes. It is recommended for construction companies in the building equipment industry. 【Features】 - Can be installed at corners and intersections with just one component - Easy installation by simply inserting the fixing bar - Lightweight (made of resin), making transportation on-site and high-altitude work easy - Vibration suppression effectiveness confirmed through seismic testing at 1.2 times the intensity of the Hanshin Earthquake reproduction wave *For more details, please refer to the PDF document or feel free to contact us.

Introducing the drainage vent valve from the brand "IValue," which specializes in quality delivery by Ishiguro. The "Easy Vent" is a magnet-type drainage vent valve that can be installed at a low position. The valve is sealed by a magnet, allowing installation at an angle of up to 45°. *It can be tilted in any direction. Under normal conditions, the valve is kept closed by the repulsion of the magnet, blocking odors in the pipe. During drainage, the negative pressure in the pipe opens the valve, allowing air to enter. 【Features】 ■ Can be installed at a low position ■ Supports tilting up to 45° ■ No need for freeze protection ■ Sealed by magnetic force ■ Blocks odors *For more details, please refer to the PDF document or feel free to contact us.
