エムアンドエム Company Overview

At M&M Corporation, we have experience in handling and selling Parker Hannifin's PUSH-LOK hoses. PUSH-LOK hoses are industrial hoses suitable for air, water, oil, and more, used in a wide range of applications such as factory equipment and mold temperature control lines. The 801 series and 7212 series we are introducing can be selected based on the application and usage conditions. Main Applications: - Mold temperature control lines - Industrial air piping - Cooling water piping - Oil piping - General industrial machinery In addition to standalone hoses, we also handle quick connectors such as the MMG200 series (compatible with DME200), MMG300 series, and Parker200 series. We offer various series with a pressure resistance of 14 kg/cm² and a heat resistance of 204°C, and we can also provide proposals that combine hoses and fittings.

"Water only leaks at the moment of connection..." This kind of symptom is one of the common troubles seen with quick couplings for mold temperature control. It is often assumed to be a failure of the coupling body, but in reality, cases where the cause is deterioration of O-rings or gaskets, incorrect sizes, or material selection mistakes are not uncommon. For example, - The O-ring is hardened or worn. - The size of the replacement gasket does not match. - A material unsuitable for glycol or oil is being used. - Foreign objects are causing jamming or insufficient locking. In such conditions, the sealing performance decreases during connection or pressurization, leading to water leakage. This document provides a clear explanation with illustrations on: - The mechanism of water leakage occurring only during connection. - The causes of O-ring and gasket deterioration. - The differentiation between silicone gaskets and Viton gaskets. - Key points for inspection and replacement to prevent water leakage. Additionally, we introduce related products that are helpful for water leakage prevention, such as **replacement gaskets compatible with the Parker 200 series (P200-6AY, P200-9AY)**, quick couplings, and temperature control hoses.

Do you think that 'water leaking from the joint = failure of the joint itself'? Water leaks in mold temperature control equipment are related to multiple factors, not just the joint body, including O-rings, gaskets, nipples, and hoses. For example, do you experience any of the following symptoms? ✔ Water leaks only at the moment of connection ✔ Water droplets or seepage around the joint ✔ No improvement even after replacing the gasket ✔ Leaks reoccur in high-temperature equipment In reality, common causes include: Hardening of O-rings and gaskets, Insufficient locking of worn connection parts, Scratches on the outer circumference of the nipple, Deterioration or poor tightening of hoses, Selection of sealing materials unsuitable for the operating environment. This document provides a detailed explanation of the mechanisms behind water leaks, inspection methods, differences in gasket materials (silicone and Viton), and key points for preventive maintenance. Additionally, we introduce products that are useful for overall equipment maintenance, such as replacement gaskets compatible with the Parker 200 series, DME-compatible joints, and temperature control hoses.
