Video Transcript for LaSalle Bristol RV Sewer - Hose Adapters and Fittings - 34466V20A3B Review

Speaker 1: Today we're taking a look at a waste valve cap. This unit adds or replaces a cap for the waste valve on your RV. It is designed for 3 inch waste valves. The bayonet fitting is designed to simply twist onto the waste outlet's lug fitting. This is a two-prong bayonet-style fitting. It's made from a durable plastic construction.

It's black in color. It does include the clear tether strap, so that way you don't misplace or lose the cap. Right here it has the internal seals which once secured onto the waste outlet's lug fitting. The seals really help ensure leak-proof connection, so a nice leak-proof fit. The product is also made in the USA.

That's gonna do it for today's look at the waste valve cap.

Replacement Bayonet Cap for LaSalle Bristol Waste Valve - 3" Diameter - 8" Strap - 34466V20A3B

Average Customer Rating:  4.9 out of 5 stars   (73 Customer Reviews)


I bought this to replace the original one where one of the "ears" broke off. To be honest, the plastic string may have gotten underneath the cap and between the waste valve. When I turned it with brute force to fasten the cap to the waste valve, I may have broken it. So, I always look for the plastic string now when I put the cap on the waste valve. I ordered two even though I only needed one. So, Now I have a spare. The cap says, "Bristol" on it,just like the waste valve. Fast shipping and exactly what I needed. Thank you!

The Bristol Waste Cap is still working great. It does not leak. That is the important feature.

These Jacks arrived quickly. We installed soon after and the quality was better than the original jacks on my camper.


This was an exact fit for my broken cap. The eTrailer website let me find the exact replacement I needed. eTrailer got me my part quickly with reasonable shipping costs.


We broke our waste valve off and we were concerned that we would find one that would fit. This did the trick - fit perfectly!!!


It is what I exoected and it looks like it is better made than my existing one is that broke.


Very satisfied with my order. Order was shipped in a very timely manner.


Was easy to find exactly what we needed on the webpage; quick to order and arrived quickly. Just what we needed as the plastic strap on our old one had broken. Excellent customer service and fast delivery! We can always find what we need at Thank you.


Easily found the exact replacement part for our RV waste system at etrailer. Reasonable price and quick delivery, very pleased!


Exactly as advertised and quick delivery after ordering


Got all items quickly. No parts missing. Installed and done. Thanks


Fit perfectly


Shipping was very fast. Very good communication on when the product would arrive. The RV sewer cap is the same brand I had on my trailer.


Perfect replacement. I’ve ordered several items over the years, always excellent service. Thanks


I had my travel trailer in for service and asked them to replace a broken sewer cover. It was back ordered an never came in. I went online and googled travel trailer swears cover an trailer came up. Ordered one, came with a week and was a perfect fit
Thanks etrailer, I'll be back.


works and fits as intended. Very fast d elivery


It was easy to attach - fit perfectly. It has not worn during this year. All good.


My order from ETRAILER came with one piece broken.
After contacting them it was immediately taken care of with the shipping of a new piece!
Great customer service! Will use them for future purchases because of their great customer service!!
Thank you ETRAILER !!


Exact replacement for the original OEM part


This is exactly what I needed and had no luck finding it anywhere else! Also, I received it in less than a week from when I ordered it. Couldn’t be more pleased with my purchase.


Excellent Service, all 4 parts arrived within 3 days of ordering with everything in perfect condition. Will definitely use etrailer in future if I need parts.


Excellent service with prompt order notification and 2 day receipt of factory original gray/black tank bayonet cap. Thank you


Always enjoy getting new stuff, and stuff for my trailer is no exception! Items were packed extra well, the right items in the box and arrived on time! Can’t ask for better service!


I always buy from you guy's because I know you'll have the oem part I need, and won't have to wait a month to get it!


I suspect that these parts break if one is not very careful with them. This is my second one to break.

Have owned 1 year now without any issues. Very satisfied
