APPLICATION
The MEPCO Stainless Steel Bucket Trap operates efficiently with
pressures up to 400 psi and is applicable to all types of medium
and high pressure steam systems. Its purpose is to efficiently
drain condensate, vent air and prevent the flow of steam into the
return piping. The Swivel Connector as found in the Model
OBHSS-UNIV is designed to maintain the bucket in the proper
plane. This trap is easily replaced or maintained without any
disturbance to the piping connections. Typical Applications
include: laundry equipment, main drip stations, and even hard to
reach applications.

FEATURES & BENEFITS
FEATURES
1. Simple, rugged construction. Trap body and internals are made of 304 stainless steel.
The valve and valve seat are manufacturered with chrome steel to provide a long lasting
seat. The trap construction is good for working pressures up to 400 psi, and
temperatures up to 800 deg F.
2. The MEPCO Stainless Steel Bucket Trap has a weld-sealed body which is tamper-proof,
maintenance-free, and protects against leakage, freezing conditions and waterhammer.
3. Unlike standard bucket traps, the MEPCO Stainless Steel bucket trap is self priming.
The OBHSS-UNIV Series MEPCO Stainless Steel Bucket Trap requires no additional piping in
either plane. The swivel connector allows for the trap to be mounted in the vertical plane
regardless to the plane of the piping. The OBHSS series trap is available in Socket Weld or
Threaded connections for both the OBHSS-UNIV and OBHSS-1400/2400 series. Swivel
Connector sold separately.
