Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. Also known as ultra-high-purity fittings, they’re packed in a Class 100 clean room, cleaned, and double bagged. They are commonly used in semiconductor applications. Fittings use a metal gasket (sold separately), which generates fewer particles than a rubber gasket and creates a strong seal in high-pressure and high-vacuum applications. Fittings are 316 stainless steel for excellent corrosion resistance.
To assemble, place a gasket between the gasket ends before gently rotating the female-threaded fitting onto the male-threaded fitting. Tighten until 1/8 of a turn past finger tight.

Retaining
Tabs
Nickel gaskets are softer than stainless steel gaskets, so they won’t wear down sealing surfaces as much, and they’re easier to tighten. They’re reactive to carbon monoxide and ozone, so they shouldn’t be used with those chemicals.
Hard and heat resistant, stainless steel gaskets can be used in a wider range of applications than nickel gaskets such as carbon monoxide and ozone. However, they’re harder to tighten than nickel gaskets, and they’ll wear down sealing surfaces more quickly.
Silver-plated stainless steel gaskets are softer than unfinished stainless steel gaskets, so they won’t wear down sealing surfaces as much, and they’re easier to tighten. However, they oxidize when exposed to air, and silver particles might flake off during assembly.
Gaskets with retaining tabs stay in place during installation, so you don’t have to hold the gasket while fastening fittings together. This also means they’re less likely to scratch or nick your fittings by rotating during installation.

Clean Room Hairnets
Also known as bouffants, these hairnets keep hair contained to reduce contamination. Designed for use in Class 100 clean rooms, they keep pollutants such as hair, dust particles, and microbes from contaminating a space. Use these hairnets for short- to medium-length hair.

Disposable Clean Room Hoods
Designed to meet clean room standards, these hoods prevent dust particles and microbes on you from contaminating a space. Made of Tyvek polyethylene, they hold up to limited contact with nonhazardous liquids, such as water and paint spray. The heat- and pressure-bonded fibers make these hoods soft yet strong. You can throw them out after you’re done using them.

Clean Room Hoods
Prevent dust, microbes and other pollutants from contaminating a clean room. When laundered to clean room standards, these hoods can be reused up to 100 times. Wash them prior to first use and after each use.
All hoods are suitable for use in clean rooms rated to both Federal Standard and ISO classes. In both standards, clean rooms with lower class ratings have fewer contaminants.
Polyester/carbon fiber hoods discharge static electricity and prevent the buildup of static from harming electronic equipment.
Polyester hoods withstand liquid splashes and abrasion.
