Medium-Pressure Stainless Steel Threaded Pipe Fittings
Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.
316 stainless steel fittings have excellent corrosion resistance.
Alloy 20 stainless steel fittings have the best corrosion resistance of all the stainless steel fittings we offer. Alloy 20 stainless steel is also known as Carpenter 20 and resists cracking from stress and corrosion.

Ultra-High-Temperature Quartz Glass Tubes
- Color: Clear
- Max. Temperature: 2000° F
- Fabrication: Annealed
Blistering temperatures won’t melt these quartz tubes, and rapid temperature shifts won’t cause them to crack. Even tougher than borosilicate, they can be used in furnaces and ovens heated up to 2000° F. These highly pure tubes are often used in laboratories because they won’t leach impurities into samples or contaminate chemical reactions. Quartz tubes are optically clear and have excellent UV transmission, making them ideal for UV purification systems.

Borosilicate Glass Tubes
- Color: Clear
- Max. Temperature: 445° F
- Fabrication: Annealed
Also called Pyrex and Schott glass, this glass resists clouding and pitting and is highly chemical and heat resistant. With a low rate of thermal expansion, it stays dimensionally stable during changes in temperature.
