What is the EC 992 Billet Barb Fitting?
The EC 992 Billet Barb Fitting is a billet aluminum fitting designed to connect a catch can to the 1/2" hose used with EC 280, 281, and 282 PCV systems.
It features a 1/2" hose barb on one end and 1/4"-18 NPT male threads on the other.
What size hose does the EC 992 fitting use?
The EC 992 uses a 1/2" hose barb. It is specifically sized to work with the 1/2" hose used with EC 280, 281, and 282 PCV systems.
What size are the threads on the EC 992?
The catch can side of the fitting uses: 1/4"-18 NPT male threads. The catch can must have a compatible 1/4"-18 NPT threaded port.
What size hole do I drill for the EC 992?
If you are modifying a catch can to accept the fitting, drill a: 7/16" diameter hole The hole should then be tapped with a 1/4"-18 NPT pipe tap.
How do I install the EC 992 into a catch can?
The basic installation procedure is:
- Drill a 7/16" hole in the catch can.
- Tap the hole using a 1/4"-18 NPT tap.
- Thoroughly clean the catch can and remove all chips and debris.
- Apply an appropriate thread sealant to the fitting.
- Thread the EC 992 into the catch can.
- Tighten securely without overtightening.
Can I install the EC 992 into a catch can that already has a 1/4 NPT port?
Yes. If the catch can already has a properly sized 1/4"-18 NPT female port, the EC 992 can be installed without drilling or tapping.
Do I need an adapter to connect the EC 992 to EC PCV hose?
No. The 1/2" barb is designed to directly match the hose used with EC 280, 281, and 282 PCV systems, eliminating the need for a separate hose-size adapter.
What EC PCV systems is the EC 992 compatible with?
The EC 992 is designed to match the hose used with:
- EC 280 PCV
- EC 281 PCV
- EC 282 PCV
Can I use the EC 992 on a mini bike?
Yes. The EC 992 is well suited for mini bike catch can and crankcase ventilation systems using 1/2" hose.
It can be used with compatible Honda GX200, Clone, Predator, Tillotson, Wildcat, and other small-engine performance applications.
Can I use the EC 992 on a go-kart?
Yes. The fitting is ideal for go-kart and racing kart catch can systems, particularly applications using 1/2" PCV or crankcase ventilation hose.
Does the EC 992 fit a Honda GX200?
The fitting can be used on a Honda GX200 when the engine is equipped with a compatible PCV or crankcase ventilation system using 1/2" hose.
The EC 992 is a catch can fitting rather than a direct engine-specific replacement part.
Does the EC 992 fit a 196cc Clone engine?
Yes, it can be used with compatible 196cc Honda Clone engine PCV and catch can systems that use 1/2" hose.
Does the EC 992 fit a Predator 212?
Yes, the EC 992 can be used on compatible Predator 212 crankcase ventilation systems when the system uses 1/2" hose.
Can the EC 992 be used with other small engines?
Yes. The fitting can be used on many small-engine applications as long as the ventilation system uses 1/2" hose and the catch can can accept a 1/4"-18 NPT fitting.
What is a catch can used for?
A catch can is used to collect oil mist, condensation, and crankcase vapors from an engine's crankcase ventilation system.
It can help prevent oil vapor from being routed directly into the engine's intake or accumulating in other parts of the ventilation system.
Does the EC 992 itself function as a catch can?
No. The EC 992 is the fitting used to connect the hose to a catch can. The catch can itself is sold separately unless specifically stated otherwise.
Is the EC 992 made from billet aluminum?
Yes. The fitting is machined from billet aluminum for a lightweight and durable construction suitable for performance and racing applications.
Why use a billet fitting instead of a standard brass fitting?
The billet aluminum construction provides a lightweight, compact fitting that complements performance engine and catch can installations.
It also provides a clean solution when matching an aluminum catch can and small-engine racing components.
Can I use thread sealant on the EC 992?
Yes. An appropriate NPT thread sealant should be used to help seal the tapered pipe threads.
Avoid applying excessive sealant that could enter the catch can or ventilation system.
How tight should the EC 992 be?
The fitting should be tightened enough to create a secure connection and seal, but do not overtighten.
Catch cans are often made from relatively thin aluminum or other lightweight materials. Excessive torque can pull or damage the newly tapped NPT threads.
Why shouldn't I overtighten the fitting?
The 1/4"-18 NPT threads are tapered and create a seal as the fitting is tightened.
Overtightening can damage the fitting, crack the catch can, or pull the tapped threads out of a thin-wall catch can.
Can I drill and tap any catch can for the EC 992?
Not necessarily.
The catch can material must have sufficient wall thickness and structural strength to safely hold 1/4"-18 NPT threads.
Thin-wall containers may require a welded or reinforced bung rather than directly tapping the material.
What tools are required to install the EC 992?
For a catch can without an existing 1/4"-18 NPT port, you will need:
- Drill
- 7/16" drill bit
- 1/4"-18 NPT pipe tap
- Appropriate cutting fluid
- Thread sealant
- Wrench suitable for the fitting
Clean all chips and debris from the catch can before connecting it to the engine.
Can the EC 992 be used for a fuel line?
The EC 992 is designed primarily as a PCV and catch can fitting. It should not be used for fuel-system applications unless the fitting, hose, sealant, and complete system have been specifically verified as compatible with the fuel being used.
What is the difference between 1/4 NPT and 1/4 inch straight threads?
1/4"-18 NPT is a tapered pipe thread. The fitting is designed to seal as the tapered threads engage with the matching female NPT threads.
It is not the same as a 1/4" straight-thread fitting.
Is the EC 992 a universal 1/2" hose fitting?
It is a 1/2" hose barb with 1/4"-18 NPT male threads, so it can be used in many applications with those specifications.
However, the intended EC application is connecting EC 280, 281, and 282 PCV hose to a catch can.
What is included with the EC 992?
The product includes:
1 × EC 992 Billet Barb Fitting
The catch can, PCV hose, clamps, drill, tap, and other installation components are not included.
What should I verify before ordering?
Verify that your application uses:
- 1/2" PCV hose
- A catch can capable of accepting a 1/4"-18 NPT fitting
- Adequate catch can wall thickness for tapping
- An appropriate location for the fitting
For custom installations, make sure all drilling and tapping operations are completed before connecting the catch can to the engine.
Is the EC 992 good for racing applications?
Yes. The EC 992 is designed for performance and racing engine ventilation systems and is particularly useful on go-karts, mini bikes, and small-engine racing applications using EC PCV systems.
Why use the EC 992 instead of an adapter?
The EC 992 provides a direct connection from 1/2" PCV hose to a 1/4"-18 NPT catch can port. This eliminates an additional adapter and can create a cleaner, more compact installation with fewer connections.
