What size thread is a fl820s?
There isn’t a universal thread size for FL820S. The correct size depends on the manufacturer and the specific product line that uses the FL820S model number. To be sure, consult the official specifications or measure the threads directly. This article explains how to identify the right size and what to check if the model varies by supplier.
Understanding what the FL820S designation can refer to
The label FL820S is used across different brands for different parts, from fittings to adapters and mechanical components. Because the thread size is not standardized across all uses, the exact size must be verified for your particular item and supplier. In practice, you may encounter multiple possibilities depending on the intended application and the equipment it accompanies.
Potential contexts for FL820S
Without a single universal reference, the FL820S code could appear on fittings, housings, connector outlets, or mounting hardware from various manufacturers. The only reliable way to confirm is to locate the exact product documentation for the precise unit you own or plan to purchase.
How to determine the correct thread size
The following steps help you identify the correct thread size when documentation is unclear or unavailable.
- Locate the official product specification sheet or user manual for the exact FL820S variant you have. Look for entries labeled “Thread size,” “Mounting thread,” “Port size,” or “Connector thread.”
- Examine the packaging, label, or hardware packaging insert for a listed thread specification or compatible accessory references.
- Measure the thread with calipers and a thread gauge. For metric threads, measure the outer diameter and pitch; for imperial threads, determine threads per inch and the major diameter.
- Determine whether the system uses metric (M x pitch) or imperial (UNC/UNF, etc.) standards and compare against standard sizes to narrow the match.
- If you cannot find the size from documents or measurements, contact the manufacturer or supplier with the full model code (including any suffixes) and a clear photo of the threads.
Following these steps will help you confirm the correct thread size for your FL820S or determine if a compatible adapter or replacement part is required.
Common thread standards you might encounter
To guide your comparison, here are typical thread size families that commonly appear in consumer and industrial parts. The exact fit for FL820S will depend on the specific product line.
- Metric: M3, M4, M5, M6, M8, M10, M12
- Imperial (inch-based): 1/4-20, 5/16-18, 3/8-16, 1/2-13
Note that many specialized or proprietary components may use nonstandard or uncommon thread pitches. Always verify with the official documentation for your exact unit.
Still unsure? How to get precise information
When in doubt, the most reliable path is to obtain the precise documentation for the exact FL820S variant you own. If you are purchasing a replacement, request the manufacturer’s data sheet and verify the thread size before ordering. Photos of the thread area and the overall component can also help a supplier confirm compatibility.
Summary
The FL820S does not have a single universal thread size. The correct size depends on the maker and the specific product variant. To identify it, consult official specs, carefully measure the threads, and, if needed, contact the manufacturer with your exact model code. By following these steps, you can avoid mismatches and ensure a proper fit for your application.
What is the thread on a standard oil filter?
The most common oil filter thread sizes are 3/4"-16 (standard) and M20 x 1.5 (metric). However, other common sizes exist, such as 13/16"-16 and 5/8"-18. It's crucial to confirm the exact size for your vehicle before purchasing a filter to avoid damage, as using the wrong size can cause leaks or a sudden loss of oil pressure.
Common thread sizes
- 3/4"-16: A widely used standard size, often found on American-made vehicles.
- M20 x 1.5: The most common metric thread size.
- 13/16"-16: Another standard size, sometimes found on different engines.
- 5/8"-18: A less common size, but still used on certain engines, particularly some European and classic British cars.
How to find your car's oil filter size
- Check the old filter: Look for a part number or thread size printed on the old filter.
- Use an open-end wrench: If you can't find a size on the old filter, try slipping a 3/4" open-end wrench over the mounting threads. If it fits, you likely have a 3/4"-16 filter. If not, you may have a metric thread.
- Consult your vehicle's manual: Your owner's manual will specify the correct oil filter size and part number for your car.
