Barnes & Jones Trap Kits and Capsules

Inverted Bucket & Float and Thermostatic Steam Traps & Repair Kits

Four repair parts for Barnes & Jones steam traps are listed on BoilerSupplies.com: two F&T kits, one of them in-line, and a standard and a converted capsule. They are for the mechanic who rebuilds a trap rather than replacing it. Two things decide the order: the F&T body style, in-line or standard, and which capsule the thermostatic trap carries now. Photograph the trap and the old element, then order.

About Barnes & Jones Trap Kits and Capsules

Barnes & Jones is a steam trap maker headquartered in Randolph, Massachusetts. It introduced its first line of thermostatic steam traps in 1902, and its traps drain condensate and hold back steam in steam heating systems.

BoilerSupplies.com carries parts for two kinds of Barnes & Jones trap. F&T traps get a kit for the standard body and a kit for the in-line body. An in-line trap has its inlet and outlet on one axis, so it sits straight in the pipe run. Thermostatic traps get a steam trap capsule, listed in a standard version and a converted version. The converted capsule is for a trap body that has been changed over from its original element. Tell BoilerSupplies.com which one the trap has, or send a picture of the element that came out.

Which Barnes & Jones kit fits a straight-through float trap?

The in-line F&T kit, when the trap is a Barnes & Jones in-line float and thermostatic trap. Mechanics often call that body a straight-through float trap, since the inlet and outlet sit on one axis. F&T is short for float and thermostatic: a float drains the condensate and a thermostatic element vents the air. The standard kit is for the other body style.

How do I know whether my Barnes & Jones trap takes the converted capsule?

The old element tells you. BoilerSupplies.com lists a standard and a converted capsule, and the converted one is for a body that no longer carries its original element. If the trap's history is known, say which one it has. If not, photograph the old element once it is out and send that.

What does a Barnes & Jones F&T kit replace?

The working internals of the trap: the float that lets condensate out and the thermostatic element that vents air, with the parts they move. A float and thermostatic kit for a Barnes & Jones trap carries them, so the cast body can stay in the line when it is still sound.

What photos does a Barnes & Jones order need?

A Barnes & Jones order needs two photos and a count. Photograph the F&T trap so the inlet and outlet show, which settles standard versus in-line. For a thermostatic trap, a picture of the old element settles standard versus converted. Add how many traps are being rebuilt and send it through BoilerSupplies.com.
