BRAKE CHAMBERS
DESIGNED, TOOLED & TESTED IN THE U.S.A.
OTR brake chambers are manufactured at an engineering‑based facility that have been manufacturing all their metal stamped components for heavy‑duty spring brakes in‑house for over 35 years. KEY FEATURES INCLUDE: • Orange stroke ALERT INDICATOR • All fasteners adhere to SAE tensile strength standards • NON‑PRESSURE HOUSING Epoxy coating of 10 ga. housing prevents long‑term corrosion/rust that powder coatings allow • Reinforced MOUNTING STUDS provide rigidity and prevent damage • DUST SHIELD keeps out foreign contaminants like dirt, sand, moisture, and prevents corrosion
• The zinc‑coated CLAMP BANDS have matched stamping for maximum seal/life. The alloy steel maintains consistent long‑life pressure
• The thick steel of the PUSH ROD‑PLATE exceeds OE standards, while the rolled edge guarantees optimal diaphragm contact. It is CNC welded for superior strength. • The heavy‑duty phosphate‑coated wire of the RETURN SPRINGS have a no‑clash design and is tested to 1,000,000 cycles • The nylon‑enforced DIAPHRAGM has a ‑65 °F arctic quality • The die cast 360 spec ALUMINUM CENTER ADAPTER has a plated push rod and precision ground microfinish for exceptional sealing function • The integrally machined grooves of the CENTER SEAL provide advanced double O‑ring sealing for long life • UP TO 4-YEAR WARRANTY
