Need a specific combination? Our engineers can design a custom y-strainer to match your exact pipeline requirements.
Our y-strainers are installed in water treatment plants, oil & gas facilities, chemical processing units, and HVAC systems across the USA, Saudi Arabia, South Africa, and Italy.
"We switched to Thriveon's y-strainers for our Houston plant. The quality is on par with Italian brands, but at 35% lower cost. Lead times are consistently 3 weeks — not 10."
— Michael T., Senior Procurement Manager, Texas Chemical Processing Facility
"The customization capability is outstanding. They machined a special mesh size and added a blow-off valve per our spec. First batch passed SGS inspection without a single NC."
— David R., Operations Director, Florida Water Utility Company

A y-strainer has a body shaped like the letter "Y" with a screen at an angle, making it ideal for horizontal or vertical pipelines with moderate debris loads. Basket strainers have a larger screen area but require more space. Y-strainers are preferred for steam, gas, and high-pressure applications because of their compact design and lower pressure drop.
It depends on the particle size you need to filter. 20–40 mesh is typical for water and general process fluids. 60–100 mesh is used for finer filtration in chemical or pharmaceutical lines. 200 mesh is available for applications requiring very fine particle removal. Our engineers can recommend the optimal mesh based on your fluid characteristics.
Absolutely. We frequently produce flanged y-strainers with ASME B16.5 Class 150 or 300 drilling, but we can also match existing bolt patterns (DIN, JIS, or customer-specific). Just send your flange drawing or bolt circle dimensions.
For standard flanged y-strainers in sizes 2″–12″, lead time is 15–25 working days. Custom sizes or special materials may require 30–40 working days. We also offer air freight for urgent orders — typically 5–7 days door-to-door.
Most y-strainers feature a blow-off connection (threaded plug or flanged) that allows you to drain debris without removing the screen. For a thorough cleaning, unscrew the cap, remove the screen, and rinse or brush it clean. We recommend installing an isolation valve upstream for easy maintenance.
Yes, we provide samples for evaluation (cost of the sample + shipping). For first-time buyers, we also offer a trial order of 5–10 pieces at production pricing to validate quality and fit before committing to larger quantities.
We accept T/T (wire transfer), L/C (letters of credit) for larger orders, and PayPal for sample or trial orders. For new customers, we typically require 30% deposit and 70% balance before shipment. Open terms (net 30/60) may be considered after establishing a track record.
Every y-strainer undergoes hydrostatic testing at 1.5x rated pressure, air seat testing, and visual inspection per ASTM standards. Material test reports (MTR) and NPT gauging reports are included with every shipment. We also accept third-party inspections (SGS, BV, Intertek) at your request.

Real feedback from procurement professionals and engineers who have used our products.
"Extremely consistent quality across multiple shipments."
We ordered 200 flanged y-strainers (4″ Class 150) over three separate batches. The dimensional tolerances, thread gauging, and pressure test results were identical every time. That kind of consistency is rare with Chinese suppliers.

"Saved 40% compared to our previous European supplier."
We had been buying Italian y-strainers for years. Thriveon's product matches the quality but at significantly lower pricing. The engineering team was very responsive when we needed to adjust the screen mesh for a specific application.
Verified Purchase · November 2025
"Excellent OEM support for custom design."
We needed y-strainers with a non-standard blow-off connection for a chemical injection skid. Thriveon's engineers designed a custom cap with a threaded port in less than a week. Prototype samples arrived in 18 days and worked perfectly.
Verified Purchase · September 2025
"Fast shipping — arrived 2 weeks earlier than quoted."
We were initially skeptical about lead times from China, but our first order of 1–8″ y-strainers was ready in 21 days and arrived at our warehouse in Ohio in 14 days via air freight. Documentation was complete and accurate.

"Great technical support from their engineering team."
When I had questions about pressure drop calculations for a steam application, their senior engineer provided detailed charts and recommended the correct mesh size. That level of support is rare from a manufacturing partner.
