PPG inch metal-rubber washers

Washers designed for sealing threaded connections. 

Metal-rubber-self-centering washers designed for threaded connections (fittings, bolts, and others). Metal-rubber washers (bonded seals) are designed to seal threaded connections - these elements are used when screwing all types of fittings into the actuator body, valve manifold, or another element with an internal thread. Washers ensure 100% tightness and connection reliability. Originally packed in bags of 100 pcs (smaller quantities can be ordered). 

What are PPG inch washers?

PPG inch washers are specialized sealing elements designed for BSP inch threads, combining the properties of metal and rubber. They are commonly used in hydraulic and pneumatic systems where precise sealing of threaded connections plays a key role in ensuring system reliability. Their design, based on the combination of a metal ring with a flexible rubber insert, makes them perform excellently in difficult working conditions such as high pressures, variable temperatures, or the presence of chemicals.

Characteristics of PPG inch washers

PPG inch washers are characterized by the following features: Dual-material construction: Made of durable metal (usually steel) combined with a high-quality rubber insert, which ensures durability and flexibility. Precise fit: Designed according to inch dimensions, making them the ideal choice for threaded connections in hydraulic systems using the inch standard. High pressure resistance: Perfectly seal systems operating under heavy load, eliminating the risk of leaks. Chemical resistance: The rubber used in the production of the washers ensures high resistance to various oils, greases, and hydraulic fluids. Versatility of application: Suitable for both static and dynamic connections.
