​Data sheet

2. Description

The model 75N is designed for solving the corrosion problems which usually happen in low pressure piping systems. Our couplings are produced in good quality reinforced nylon, injection molded by high temperature. It features its high strength and toughness, perfect corrosion resistance performance. They're widely used in ultra filtration ( UF ) membrane system and other water treatment, seawater desalination equipment.

Our flexible couplings give contractors, engineers and owners an unmatched competitive edge cutting piping system installation time, and making installations safer. These grooved pipe joints offers you with innovative solutions

acrossdiverse business lines including building services, clean water and waste water, fire protection, industrial

construction, maritime, mining, oil, gas and chemical, power generation, as well as custom castings.

Quick joints housing materials:

Nylon, other composite, plastic material upon demands.

Bolts&Nuts:

• Type 304 stainless steel track bolts and nuts to ASTM F-593
• Type 316 stainless steel track bolts and nuts to ASTM F-593
• Type 316 stainless steel track bolts ASTM A193 B-8M with silicone bronze heavy duty nuts to ASTM B98 C65100​

Rubber Gaskets or seals:

The gasket seals is C-shaped, made of standard gasket EPDM (ethylene propylene diene monomer) for cold water, hot water, rare acid, oilfree air and multiple chemical product (-50~150 ).It is not suitable for medium like petroleum
