In-Line Strainers
Ron-Vik in-line strainers have been the industry standard for cost effective
straining and filtering since they were introduced over thirty years ago.
Applications are wide ranging and include: agricultural sprayers, pressure
washers, floor scrubbers, drinking water pre-filters, medical devices and car
washes.
• Available in many different sizes from 1/8" to 1 1/2"
• Female, male, hose barb and quick connect ports
• Materials include 6/6 nylon, 20% glass filled polypropylene and clear nylon
(for bowls)
• Elements available in 20, 40 or 80 mesh T304 stainless steel, caged
synthetic screens or 70 micron PE
• 3 standard gasket materials
Customization Available
• Company name or logo molded on the top
• Color of the material for the top and bowl
• Thread size on the ports of the top
• Mesh size of the screen
• End treatment of screen
Custom injection molded parts require a 1,000 piece minimum. The minimum for
custom screens alone is 100 pieces. There may be additional charges for
engineering costs.
Tops
In-line strainer tops are available in either black 20% glass filled
polypropylene or white 6/6 nylon materials. Ron-Vik offers a variety of port
types and sizes.
Male NPT - available in 1/8", 1/4", 3/8" and 1/2"
Female NPT - available in 1/8", 1/4", 3/8", 1/2", 3/4", 1", 1 1/4" and 1
1/2"
Hosebarb - available in 3/16", 1/4", 3/8"
Quick connect fitting - available for 1/4" and 3/8" OD tubing
Existing tooling available for reversed arrow
direction, and BSP threads. Minimums apply.
Bowls
Ron-Vik offers five sizes of bowls, one for each of the product series. The
top-bowl connection is a buttress thread to prevent cross threading. For
application flexibility, the bowls are offered in 20% glass filled
polypropylene, 6/6 nylon and clear nylon.
The chart below outlines the major differences between these materials.
Chemical compatibility for your individual use should also be confirmed.

Elements
Ron-Vik offers three types of elements:
• Wire mesh screen - the most common element, utilized in all in-line strainer
assemblies. Standard mesh sizes are 20, 40 and 80. For strainer area please see
the corresponding series data. Options include:
|
– Type 304 stainless steel is standard, however, Type 316 stainless steel
and monel are also offered
– Edges can be hemmed, soldered or molded with PVC
– Finer mesh reinforced with a back up screen
|
• Color coded synthetic caged screens available in 20, 40 and 80 mesh in both
polypropylene and nylon.
• Polyethylene filter (PE) - offered for the low profile, intermediate and
large series. This filter is rated at 70 microns and is depth type filter
making it non-cleanable.

Gaskets
Three gasket materials are offered to meet the various needs of Ron-Vik's
customers. The gaskets are color coded to eliminate confusion when ordering
replacements. The chart outlines the basic characteristics of the gaskets.

Low Profile and Mini Series
Low profile in-line strainers require a minimum amount of space. To increase
filter area the low profile tops can be matched with a longer bowl, (referred
to as the Mini Series). Common applications for these strainers include home
water treatment systems, floor cleaning equipment, and medical supply. The
chart below shows reference dimensions for assemblies.

Regular Series
This series is the most commonly used due to compact size yet large filter
area. Some of the applications for this series include, dental supply,
commercial and industrial pumps, agricultural and marine. The standard port is
NPT. This series is also available with Hosebarb, BSP (Higher minimums apply).

Technical Information
Cleaning Requirements
All wire mesh elements can be easily cleaned or replaced, without removing the
entire strainer from the line, by removing the bowl. Do not use chemicals
incompatible with the plastic components for cleaning.
Filter Shipments
In-line strainers can be shipped either as complete assemblies or as individual
components. Strainers are shipped bulk unless otherwise quoted.
Mounting
Strainers may be mounted in any orientation providing that they are adequately
supported to protect from undue stress and vibration.
Pressure Ratings
All of Ron-Vik's in-line strainer assemblies have been proven to perform at
pressures up to 150 PSI at 70°F and 100 PSI at 125°F.
Pressure Spikes
Ron-Vik in-line strainers are not intended for applications where pressure
spikes in excess of maximum pressure ratings can be expected.
NSF
Most of Ron-Vik's in-line strainers are eligible for NSF certification as part
of your product. They are not individually NSF certified. Please contact us for
specific information.
* Minimum order quantities and additional charges including engineering may
apply.
