Ohio Fabricators manufactures strainers with all plated steel connections and those with nylon connections. Sometimes the question will arise as to which one works better in my system?
Connection specifications
Connection heads can be made from all plated steel (OFCO H7000 series).
Connection heads can made with glass reinforced nylon type 6 (OFCO P7000 series).
Plated steel heads can withstand a higher temperature than nylon. However, this is a non-issue because the “weakest link,” so to speak, is the highest peak temperature of the epoxy used to keep the strainer together. The maximum temperature of a strainer is approximately 340°F regardless of the type of connection head.
Plated steel heads are stronger than nylon but less corrosion resistant. Plated steel heads may be more durable in systems where there is a lot of vibration.
Strainers with nylon heads are less costly.
A final reason, that plated steel suction strainers are used vs. those with nylon heads is that simply, some operators, maintenance personnel, or engineers just prefer them and feel more comfortable using all steel heads.
Overall, as for functionality of the strainer, both are equal in performance when it comes to filtration. Therefore, the choice is up to those selecting which style they prefer to use. It is simply that.

You’ve most likely visited our website and taken a look at our new suction screens. They will not corrode, are available in various pipe sizes and mesh sizes, and are made at our plant in the USA.
They have been widely used in areas such as…
Low-flow hydraulics
Chemical industry where non-caustic fluids are used (fluids used must be compatible with the epoxy in the suction screens).
Water applications. They are made of glass reinforced nylon and stainless steel.
Disaster recovery. Merely thread them onto a suction hose to remove unwanted flooding of water to prevent excessive debris blocking suction.
Industrial paint industry. Used with paint sprayers that pick up paint from five gallon buckets or larger drums for spraying.
Coolants. Where coolants are gently sprayed on metals to coat them preventing corrosion (This is not a suction application but can be used in this manner).
Insect control. Used in various insect control sprayers.
Building maintenance. Used in floor cleaning machines if there are equipment space issues where larger strainers will not fit.
