Titanium Threaded Pipe Fittings
Titanium has similar strength to steel, but is approximately 40% lighter. It has better corrosion resistance than most stainless steel alloys and can handle corrosive substances, such as salt water and acids.
Threaded female x butt weld straight adapters are also known as half couplings.
- For Use With: Air, Oil, Salt Water, Water, Natural Gas
- Specifications Met: ASME B16.11, ASTM B348
Plastic Clean Room Hinges
Keep environments free of contaminants—with plastic hinge leaves and a metal pin, there's no metal-to-metal contact that can release particles as hinges open and close. The hinge pin is nonremovable to deter tampering.

Piano Hinges without Holes
Between
Hinge Leaves
Longer than other hinges, piano hinges run the entire length of doors and lids for strength and durability. These hinges have a standard clearance—when they are closed, the distance between the leaves is about the same as the pin diameter.
Titanium hinges are more corrosion resistant than 316 stainless steel. They also have good acid resistance.
Note: Prices are 15% to 20% lower when you buy 10 or more hinges of the same size.
